What is the Range Tribune HE?

Range Cylinders is a Birmingham-based manufacturer that has been building hot water cylinders for British homes for over seven decades. The Tribune HE is their flagship high-efficiency unvented range — duplex stainless steel (typically 2304 or 2205 grade), TIG-welded, pressure-tested and factory-foamed with high-density polyurethane to minimise standing heat loss. Every cylinder ships with a 25-year tank warranty when installed by a G3-certified engineer and serviced annually.

The Tribune HE family covers every common UK install scenario. Standard Indirect is the workhorse — paired with a gas system or heat-only boiler via a single coil, this is the version that lands in most London 2–4 bed homes. Direct variants ditch the coil for twin immersion heaters, suited to all-electric flats and Economy 7 tariffs. Solar twin-coil pairs a renewable input with a boiler back-up. Heat Pump variants oversize the coil for low-grade flow temperatures. Slimline drops the diameter to 475 mm for tight London cupboards, and Horizontal lets you mount the cylinder on its side in lofts or low-ceiling spaces.

The case for the Tribune HE in London is straightforward — it matches Megaflo and Gledhill on warranty and compliance, sits 10–15% below them on RRP, and the manufacturer is two hours up the M40 if a warranty claim ever needs handling. For hot water cylinder replacement where the budget matters as much as the spec, the Tribune HE is the value pick that gives nothing up on the long-term warranty.

Range Tribune HE — the full range

Six variants cover almost every London install scenario. Survey first — the variant choice is set by the boiler type, the cupboard dimensions, and any renewables already on the property.

VariantUse caseSizes available
Tribune HE IndirectMost common — paired with a gas system boiler. Single coil for primary heating.90, 120, 150, 180, 210, 250, 300L

Tribune HE SolarTwin-coil for solar thermal pairing. Lower coil takes solar gain, upper coil takes boiler back-up.180, 210, 250, 300L
Tribune HE Heat PumpLarger lower coil sized for low-grade heat pump flow temperatures (45–50°C).180, 210, 250, 300L

Tribune HE HorizontalHorizontal mount for low-ceiling cupboards and loft installs. Same duplex stainless construction.150, 180, 210L

Sizing — what litreage do I need?

Range follow the Hot Water Association rule of thumb: 35–45 litres of storage per occupant, plus 50 litres for any property with a daily-used bath. Over-sizing wastes standing heat. Under-sizing means cold-shower complaints in the second bathroom. The recommendations below cover most London property types.

Real Tribune HE jobs — worked examples

Five anonymised Tribune HE jobs from the last twelve months across London, with the brief, the work done and the final fitted figure.

Battersea, SW11 — Tribune HE 180L T&P discharging on heat-up

Customer reported steady drip from the tundish 18 months after a Tribune HE install elsewhere. On-site diagnostic: expansion vessel pre-charge collapsed to 1.4 bar (factory spec 3.0 bar). External 18L vessel fitted on the cold leg, recharged to manufacturer pressure, system bled, T&P witnessed-tested clean. 95 minutes on site. £265 inc. VAT. Tribune warranty kept intact because the original install was on a Benchmark logbook.

Clapham, SW4 — like-for-like Tribune HE 210L swap

1990s vented cylinder + loft tank serving a 4-bed Victorian terrace with two bathrooms. New mains supply already in 22 mm copper, so a straight conversion to a Tribune HE 210L Indirect. Removed loft tank, capped redundant feeds, fitted Tribune HE with full G3 group, discharge through external wall to gully. Day-and-a-half install. Final invoice £2,140 inc. VAT, 25-year tank warranty registered with Range that afternoon.

Camden, NW1 — Tribune HE Slimline 150L in narrow cupboard

Mansion block airing cupboard 510 mm wide — too narrow for a standard Megaflo. Specced a Tribune HE Slimline 150L (475 mm diameter) for a 2-bed flat with one bathroom and a separate shower. Install completed in a single day, discharge piped through an existing external wall vent. £1,795 inc. VAT.

Wandsworth, SW18 — Tribune HE Solar twin-coil pairing

Roof solar thermal install on a 4-bed home, no existing cylinder big enough to accept the panel output. Replaced an old 150L Megaflo with a 250L Tribune HE Solar twin-coil. Bottom coil to the panels, top coil to the system boiler. Set legionella cycle on the boiler to maintain 60°C overnight when solar gain is low. £2,895 inc. VAT, two-day install.

Islington, N1 — emergency Tribune HE replacement after tank rupture

Existing 15-year-old non-Tribune indirect cylinder split internally — water staining and dripping from the foam jacket. Same-day attendance, isolated the leak, drained down, source of leak confirmed as tank wall failure (warranty already expired). Quoted and fitted a Tribune HE 180L Indirect within 28 hours of the first call. £1,795 inc. VAT, hot water restored same week.

Frequently asked questions — Range Tribune HE

Why choose a Range Tribune over a Megaflo?
Range Tribune HE and Megaflo Eco are broadly equivalent — both are UK-supported duplex stainless cylinders with 25-year tank warranties when serviced annually. Tribune typically lists at 10–15% below Megaflo on size-for-size, which is why most fitted-price quotes from London engineers using Tribune come in £100–£200 lower for the same size. Megaflo wins on outright London parts depth — every plumbers' van carries a Megaflo expansion vessel, PRV and immersion. Tribune wins on price, slimline options, and the breadth of variants (solar, heat pump, horizontal). For a straightforward 180L London swap, Tribune HE is the value pick that does not give anything up on warranty or compliance.
Is the Range Tribune HE made in the UK?
Yes — Range Cylinders has been manufacturing in Birmingham for over 70 years. The Tribune HE is fabricated from duplex stainless steel sheet (typically 2304 or 2205 grade), TIG-welded and pressure-tested before factory-foaming with high-density polyurethane. UK manufacturing means shorter lead times for non-stock variants (Slimline, Horizontal, Solar twin-coil) and easier warranty handling because the support desk is also UK-based. For G3 installs registered on the Benchmark logbook, Range honour the 25-year tank warranty across the full installed life.
How long does a Tribune HE installation take in London?
A like-for-like Tribune HE swap — replacing an existing unvented cylinder in the same cupboard, with the same pipework routes — takes 4–6 hours, single-day. A vented-to-unvented conversion replacing an old vented cylinder plus a loft tank takes 1–2 days because all the supply, discharge and any electrical work is new. The big London-specific time sinks are access (rooftop airing cupboards in mansion blocks), discharge routing to outside (often the hardest part on a mid-floor flat), and stop-tap location in shared buildings. Survey first, fixed price always given before any work begins.
Do I need a G3 engineer to install a Tribune HE?
Yes. Approved Document G3 of the Building Regulations makes installation, commissioning and modification of any unvented hot water storage vessel over 15 litres a controlled service. The engineer must hold a current G3 (BPEC HWSS, LCL Awards or City & Guilds 6035) certificate, renewed every 5 years, and the work must be notified to building control either directly or through a Competent Persons Scheme (we use WaterSafe / BESCA). Any Tribune HE installed without a G3 ticket is non-compliant, voids the 25-year tank warranty, and is uninsurable for the buildings policy. Range will refuse warranty claims where the Benchmark logbook is missing.
What is the difference between Tribune HE Direct and Indirect?
Indirect cylinders have an internal coil heated by an external heat source — usually a gas system boiler. They are the default choice in London because most homes have a boiler that will outlive the cylinder. Direct cylinders have no coil — water is heated entirely by twin immersion elements running on electricity. Direct is the right call for all-electric flats with no gas connection, properties on Economy 7 / Octopus Agile tariffs, and any install where a boiler is being removed in favour of an air-source heat pump (paired with a Tribune HE Heat Pump variant). Indirect Tribunes can still accept a single immersion as a backup heat source.
Can I fit a Tribune HE Slimline in a narrow London airing cupboard?
Often yes. The Tribune HE Slimline drops the cylinder diameter to 475 mm versus a standard 545–580 mm, while keeping the duplex stainless construction and 25-year tank warranty. The trade-off is height — Slimlines run taller than the equivalent standard model to keep the same stored volume. Common sizes are 120L, 150L and 180L. A handful of London mansion blocks (parts of Maida Vale, Pimlico, Earls Court) have cupboards that will only physically accept a Slimline. The survey will tell us within 10 minutes whether your cupboard is Slimline-only, standard-OK, or wants a Horizontal variant in the loft instead.
What does the Range Tribune 25-year warranty actually cover?
Range honour 25 years on the tank (the duplex stainless cylinder body itself) and 2 years on parts (immersion, thermostat, T&P, PRV, expansion vessel). The 25-year cover is conditional on three things: G3-certified install with Benchmark logbook completed and registered, annual service every 12 months evidenced on the logbook, and only WRAS-approved components used for any later swap of the safety group. We post the Benchmark and the Building Regs G3 compliance certificate within 30 days of install. Warranty claims are submitted directly to Range — we handle the paperwork on your behalf if a tank fault is ever found.
What discharge pipework rules apply to a Tribune HE?
Two pipe sections matter — D1 and D2. D1 runs from the T&P relief valve to the tundish in 15 mm copper, with the visible 300 mm air gap above the tundish funnel. D2 runs from below the tundish to a safe external termination, one pipe size larger than D1 (22 mm typically), in copper to BS EN 1057, with continuous fall, no more than three 90° bends, and a maximum equivalent length per Range's installation manual. Termination must be visible — usually above an external gully — and not into a soil pipe, hopper or roof void. A non-compliant discharge is the single most common reason for inherited Tribune installs failing insurance survey.
How much does a Tribune HE install cost in London?
For 2026, fitted prices run £1,495 for a 120L Tribune HE Indirect up to £2,595 for a 300L on a like-for-like swap. A vented-to-unvented conversion adds £500–£800 on top because of new mains supply, vessel, discharge and loft-tank removal. Solar twin-coil and heat-pump variants carry a £150–£250 premium over the equivalent standard Indirect. Direct (all-electric) Tribunes are typically £100 cheaper than indirect on the same litreage. Every quote includes the cylinder, all safety group components, copper pipework, commissioning, Benchmark logbook, Building Regs G3 notification, removal & disposal of the old unit, and a 12-month workmanship guarantee.
Does a Tribune HE need annual servicing?
Yes — annually, and it is a condition of the 25-year tank warranty. The annual G3 service is fixed at £155 inc. VAT in London. It runs the manufacturer's 12-point checklist: expansion vessel pre-charge tested and recharged, T&P witnessed-lifted, PRV outlet pressure measured and set, inlet strainer cleaned, immersion resistance recorded, thermostat cut-out tested at 60°C, anode inspected (sacrificial magnesium where fitted), discharge pipework checked for free fall and clear termination, all isolation valves operated, and the Benchmark logbook updated. Average time on site is 60–90 minutes. Range will not honour a tank claim without an annual service record.
Can a Tribune HE work with an air-source heat pump?
Yes, but the right variant matters. The Tribune HE Heat Pump variant uses a larger surface-area coil sized for the lower flow temperatures heat pumps deliver (typically 45–50°C rather than the 70–80°C a gas boiler runs). Fitting a heat pump to a standard Tribune HE Indirect coil works but recovery time is poor and the pump runs longer. For new heat-pump installs the rule is 250L or 300L Tribune HE Heat Pump minimum, with a legionella protection cycle programmed to lift stored temperature above 60°C at least weekly. MCS-compliant cylinder sizing forms part of the heat pump install paperwork and the Tribune HE Heat Pump variant is on the eligible product list.
What if my cold mains pressure is too low for a Tribune HE?
Range specify a minimum 1.5 bar dynamic inlet pressure for the Tribune HE to deliver rated flow. We measure both static (no-flow) pressure and dynamic (kitchen tap fully open) flow during the survey. Below 1.5 bar dynamic, the options are: a mains upgrade with the water authority (Thames Water typically £300–£800), a cold water accumulator (pressure cell with a small pump — £700–£1,400 fitted) to buffer demand, or an alternative cylinder strategy such as a thermal store. We will not install a Tribune HE on a mains supply that cannot meet the minimum spec — the install would fail commissioning and void warranty.
Will my old vented pipework work with a Tribune HE conversion?
Most of the cold supply pipework can be reused — 22 mm copper is what we want feeding the cylinder anyway. What changes is everything from the cylinder up. The vent pipe is removed, the cold feed from a loft tank is replaced with a direct mains supply (often a new 22 mm run from the rising main), expansion vessel and full G3 inlet group is fitted on the cold leg, discharge pipework to outside is new. The loft tank and cold-feed tank are removed and any redundant pipework capped. Conversions are quoted at £2,495 (150L) up to £3,295 (250L) all-in, on top of the Tribune HE cylinder cost.
Are you on the Range Cylinders approved installer list?
Our G3 engineers are individually certified to BPEC HWSS (Hot Water Systems Specialist) and the company is WaterSafe approved — both of which are the credentials Range require to register their 25-year tank warranty. We install Range Tribune HE cylinders weekly across London, register every install on the Benchmark scheme and post the manufacturer's commissioning paperwork directly to Range head office. For landlords and property managers, we maintain a PPM service log so annual G3 services renew automatically and warranty conditions stay intact across the full 25-year tank cover.
What happens on installation day?
Engineer arrives between the booked window (typically 8–10am for a full-day install). First hour: isolate cold mains, drain old cylinder, strip out — including any loft tank and feed tank if it is a conversion. Hours 2–4: position Tribune HE, run new primary connections in 22 mm copper, fit expansion vessel and full G3 inlet group, run discharge pipework from T&P to outside via the tundish. Hour 5: refill, pressurise, set PRV, pre-charge expansion vessel, witness-test T&P, run up to 60°C. Hour 6: complete Benchmark logbook, file Building Regs G3 notification through our Competent Persons Scheme, demonstrate operation to the customer, leave a copy of the logbook on site and email a scanned PDF the same day. Compliance certificate posted within 30 days.
