Key highlights
⚡
3.35 m² coil — fastest heat transfer
The largest primary coil area of any copper cylinder in this directory — meaning the heat pump doesn't have to work as hard to reheat the cylinder, and reheat time is shorter. Direct impact on heat pump COP and running costs
🌡️
85°C max primary temp — hybrid ready
Suitable for hybrid systems where an oil or gas boiler tops up the heat pump in cold weather at higher flow temperatures. Future-proofs the installation
🏗️
New build default in Ireland
Specified in the majority of new A-rated homes built with heat pumps in Ireland in 2025–2026 — proven in Irish water conditions at scale

🌡️ Compatible heat pump brands
The Tribune HE HP 210L is compatible with all major air-to-water heat pump brands and is factory-recommended or shipped with Nibe S2125. See the Heat Pump Directory for full specifications, pricing and SEAI grant details on all 19 heat pumps available in Ireland.
The Range Tribune HE HP 210L cylinder itself costs approximately ~€690. Installation (remove existing cylinder, connect to heat pump primary circuit, commission immersion backup) adds approximately €400–€700. Total installed cost: typically ~€1,240. This is usually included in the overall heat pump installation quote from your SEAI-registered installer — ask for the cylinder to be itemised on the quote so you can compare against other brands.
In most cases, no — your existing cylinder should be replaced as part of the heat pump installation. Standard cylinders have small primary coils (1.5–2.0 m²) designed for boiler temperatures of 70–80°C. Heat pumps deliver water at 45–55°C and need a much larger coil (typically 2.8–3.4 m²) to transfer adequate heat at the lower temperature. The Range Tribune HE HP 210L has a 3.35 m² primary coil — specifically sized for heat pump low-temperature operation. Using a standard cylinder with a heat pump results in slow reheat, inefficient operation, and higher running costs.
Yes — the cylinder cost is included within the SEAI Heat Pump System Grant (up to €12,500 for houses switching from fossil fuel heating, from 3 February 2026). The grant is applied to the total installed system cost including heat pump, cylinder, controls, pipework and labour — not as a separate per-component payment. Cylinders are not individually grant-funded as standalone items. A BER assessment is required before the grant can be drawn down, and all work must be carried out by a SEAI-registered contractor. The Range Tribune HE HP 210L's ~€690 cylinder cost contributes toward the Central Heating Upgrade element of the grant (up to €2,000).
A heat pump cylinder is typically set to 55–60°C to balance legionella risk with heat pump efficiency. Legionella bacteria cannot survive above 60°C. Most heat pump systems include a weekly legionella protection cycle where the immersion heater in the Range Tribune HE HP 210L raises the full cylinder to 60–70°C. Day-to-day, the heat pump heats the cylinder to the setpoint temperature (often 50–55°C) — a heat pump's COP drops significantly above 55°C. The Range Tribune HE HP 210L's max primary temperature of 85°C accommodates both routine heat pump operation and legionella protection cycles. Your installer will configure the legionella cycle as part of commissioning.
The Range Tribune HE HP 210L at 210L is suited to a typical 3–4 bedroom family home. A heat pump heats the cylinder slowly over 2–4 hours (compared to a boiler's rapid reheat) — so the system is usually programmed to heat the cylinder once or twice daily, storing enough hot water for the day's demand. General guideline: allow 40–50 litres per person per day. For a 4-person household with a heat pump: 160–200L minimum. Homes with high shower use or a bath should consider 200–250L.
Copper is the most widely used material for hot water cylinders in Ireland and works perfectly well in most locations. The Range Tribune HE HP 210L's copper inner is fully compatible with heat pump operation at 45–60°C. Copper becomes less ideal in two situations: hard water areas (Dublin, Kildare, Meath — calcium deposits accelerate internal corrosion over 15–20 years) and coastal properties within 5–10km of the sea (salt air degrades exposed copper fittings). For soft water areas and inland properties, copper is the most cost-effective choice. For hard water or coastal areas, consider the Kingspan Albion Ultrasteel (duplex stainless) or Telford Tempest (stainless 304) instead.
Heat transfer through a coil depends on temperature difference (ΔT), flow rate, and coil surface area. In a boiler system, ΔT is large (boiler at 75°C, cylinder at 55°C → ΔT = 20°C) — even a small coil transfers heat quickly. In a heat pump system, ΔT is small (HP at 50°C, cylinder at 45°C → ΔT = 5°C). With a small ΔT, you need a much larger coil surface area to transfer the same heat. The Range Tribune HE HP 210L's 3.35 m² primary coil — one of the largest available — compensates for the low temperature differential, allowing the heat pump to operate at lower, more efficient flow temperatures without sacrificing reheat time. Standard boiler cylinders typically have only 1.5–2.0 m² coils — using one with a heat pump results in slow reheat and the heat pump working harder and less efficiently.
Heat transfer through a coil depends on three factors: temperature difference (ΔT), water flow rate, and coil surface area. In a boiler system, ΔT is large (boiler water at 75°C, cylinder water at 55°C → ΔT = 20°C) so even a small coil transfers heat efficiently. In a heat pump system, ΔT is small (HP water at 50°C, cylinder water at 45°C → ΔT = 5°C). With a small ΔT, you need a much larger coil surface area to transfer the same amount of heat. The Tribune HE's 3.35 m² coil compensates for the low temperature differential by providing more surface contact — letting the heat pump run at lower, more efficient flow temperatures without sacrificing reheat time.
Yes — the Tribune HE is a universal heat pump indirect cylinder compatible with all air-to-water heat pump brands including Daikin Altherma, Mitsubishi Ecodan, Samsung EHS, Vaillant aroTHERM, Grant Aerona4, Nibe S-series, Panasonic Aquarea, Worcester Bosch Greenstar and others. Some heat pump brands (Daikin, Nibe) include a matched cylinder in the package — always check whether your heat pump quote includes the cylinder or requires it separately.

The Range Tribune HE HP 210L is designed to work with the following heat pumps, solar diverters and smart energy products from our Irish directories. It is supplied as standard with Nibe S2125 installations.
Solar diverters — use surplus solar for free hot water
This cylinder has an immersion heater — which means it can receive free hot water from surplus solar. A solar diverter intercepts solar surplus before it exports to the grid and redirects it straight to your immersion, typically providing 60–80% of annual hot water from the sun. Payback is usually under 18 months.
A 4kWp solar system generates approximately 3,600 kWh/year in Ireland. With a solar diverter redirecting surplus to this cylinder's immersion heater, you can cover 60–80% of annual hot water energy for free — on top of the heat pump doing the heavy lifting.
EV charger + home battery — run everything on solar
Your heat pump and this cylinder provide low-carbon heating and hot water. Add solar panels, a home battery and an EV charger and you can power your car, your heating and your hot water from the same roof — the combined SEAI grants available reach up to €14,600.
A hot water cylinder upgrade is often the first step in a wider home energy transformation. With a solar diverter filling your cylinder for free during the day, the next natural step is an EV — charged overnight on cheap night-rate electricity or from surplus solar. See all 205+ EVs in the EV Vehicle Directory.
