Samsung Heat Pump Review: Best Value & Quietest?
Samsung’s EHS air source range has two big strengths: it’s the quietest heat pump in its class (35dB), and among the best value on the market. But the warranty terms need checking. Our honest verdict.
The short verdict
Samsung EHS heat pumps are a genuinely strong-value, class-leadingly quiet choice — with a couple of catches worth knowing. Samsung’s two standout strengths are noise (the EHS Mono HT Quiet runs at just 35 dB(A) in Quiet Mode — the quietest in its class) and value (typically £7,500–£11,000 installed, noticeably cheaper than Vaillant or Mitsubishi, and as low as £500–£3,500 after the £7,500 Boiler Upgrade Scheme grant). Performance is competitive too — a SCOP up to 4.9, eco R290 refrigerant on the Gen 7, and a high 70°C flow temperature that suits older homes with existing radiators.
The honest catches: the warranty is up to 7 years but only with a Samsung-accredited installer (2 years otherwise), and it’s parts-only; and as a newer entrant, Samsung has a thinner UK installer network than the dedicated boiler brands. So Samsung is an excellent pick for budget-conscious, noise-sensitive or retrofit buyers — just confirm your installer’s accredited status. Full review below. Our score: 4/5. (Note: this is about Samsung’s home heating heat pumps, not their tumble dryers — a completely different product.)
What this review covers
The Samsung EHS range
Samsung’s home heating heat pumps are sold under the EHS (Eco Heating System) name — all air source monobloc units. There are two ranges worth knowing:
- EHS Mono HT Quiet — the “high temperature, quiet” range (R32 refrigerant). Its headline features are a 70°C flow temperature (excellent for older homes with existing radiators) and 35 dB(A) Quiet Mode operation. SCOP up to 4.9.
- EHS Mono R290 Gen 7 — the newest range (5, 8, 12, 16kW), using natural R290 refrigerant (global warming potential of just 3), with SCOP up to ~4.9–5.10 and the best efficiency for well-insulated homes running lower flow temperatures.
There’s also a ClimateHub option that integrates the hot water cylinder and controls into a single compact indoor unit. With five capacities in the range, installers can size a system closely to your home’s heat loss. Samsung is a global HVAC heavyweight applying serious engineering to heat pumps — the EHS range is the result.
Strength 1: the quietest in its class
35 dB(A) — genuinely class-leading, and a real practical advantage
Samsung’s standout feature is noise — or rather the lack of it. The EHS Mono HT Quiet runs at just 35 dB(A) in Quiet Mode, the quietest in its class (normal operation is ~37–42 dB(A), still very quiet). For context, 35 dB(A) is quieter than a library or a fridge, and well below most rival heat pumps (typically 40–60 dB(A)). This isn’t a gimmick — it’s a genuine, practical advantage in the situations where heat pump noise matters most: where the outdoor unit sits near a bedroom or a neighbour’s window, in tightly-packed terraces or urban streets, or in conservation areas where a compact, quiet unit helps meet planning requirements. Since noise is one of the biggest worries UK homeowners have about heat pumps — and installs must pass a strict neighbour noise limit — Samsung’s quietness is a real selling point. If low noise is high on your list, the EHS Mono HT Quiet is one of the best options available.
Strength 2: among the best value on the market
Samsung’s other big strength is value. At £7,500–£11,000 installed, the EHS range is noticeably cheaper than premium rivals like Vaillant and Mitsubishi for comparable performance — making Samsung one of the cheapest quality heat pumps to both buy and run. And it’s fully eligible for the £7,500 Boiler Upgrade Scheme grant (via an MCS-certified installer in England and Wales). Because Samsung’s starting price is lower, that fixed £7,500 grant covers a higher proportion of the total — so for a straightforward install in a well-prepared home, the net cost can be as low as £500–£3,500. That’s a genuinely compelling figure. Running costs are competitive too (strong SCOP means ~£850/year heating vs ~£1,200 for gas), and pairing with a smart tariff and solar improves it further. For budget-conscious buyers — especially those maximising the BUS grant — Samsung is one of the smartest-value choices going. (See are heat pumps worth it? for the full economics.)
Specs, efficiency & retrofit-friendliness
| Spec | Samsung EHS |
|---|---|
| Noise (Quiet Mode) | 35 dB(A) — class-leading |
| SCOP | up to 4.9 (R290 Gen 7) |
| Refrigerant | R290 (GWP 3) or R32 |
| Max flow temp | 70°C (HT Quiet — old homes) |
| Capacities | 5, 8, 12, 16kW |
| Cold performance | Operates to −25°C |
| Cylinder option | ClimateHub (integrated) |
| Warranty | Up to 7yr (accredited only) |
On the numbers, Samsung is competitive across the board: a SCOP up to 4.9 (matching the better mainstream heat pumps), operation down to −25°C, and a compact design (claimed up to 30% smaller than some rivals). The 70°C flow temperature on the HT Quiet models is a particular retrofit strength — it can heat older, existing radiators effectively, giving you a buffer to upgrade radiators gradually rather than all at once, which makes Samsung one of the more retrofit-friendly brands for older homes. The R290 Gen 7 models are the greener, most efficient choice for well-insulated homes at lower flow temperatures. One honest note: while the SCOP is strong, dedicated cold-climate specialists can edge slightly ahead at very low flow temperatures.
The honest downsides
The warranty is the thing to check — and the installer network is thinner
Samsung is a strong choice, but be clear on the trade-offs:
1. The warranty (the key one). Samsung offers up to 7 years parts warranty — but only if installed by a Samsung-accredited installer. A standard install typically comes with just 2 years. And even the 7-year cover is parts-only, no labour. So if a long warranty matters to you, confirm your installer is Samsung-accredited before booking. (For comparison, this puts Samsung’s extended cover roughly in line with Worcester Bosch and Viessmann, but well short of some rivals’ 10–15 year warranties.)
2. Thinner installer & support network. As a newer entrant to UK home heating, fewer installers are trained on Samsung — and availability of installers trained on the newest R290 models is still building, so you may have less local choice, especially outside urban areas.
3. Minor points. SCOP not quite the cold-climate top performers; fewer models above 16kW for very large homes; the SmartThings app can occasionally be glitchy.
None is a dealbreaker for most homes — but the warranty terms are the one thing to clarify upfront.
Who Samsung heat pumps are right for
✓ Great for
- Budget-conscious buyers (best value)
- Maximising the £7,500 BUS grant
- Noise-sensitive sites (near bedroom/neighbour)
- Retrofitting older homes (70°C flow)
- Urban areas with good installer access
✗ Less ideal for
- Those wanting the longest warranty
- Rural areas (thinner installer network)
- Very large homes (few >16kW models)
- Absolute top cold-climate SCOP
- Buyers wanting widest brand support
In short: Samsung EHS is an excellent choice for the budget-conscious, noise-sensitive, or retrofit buyer — especially anyone maximising the BUS grant, or siting a unit near a bedroom or neighbour. If your priority is the longest warranty or the widest installer network, a dedicated heating brand may suit better. Either way, confirm accredited-installer status.

Our verdict
Frequently asked questions
Are Samsung heat pumps any good?
Yes — strong on two fronts: value (cheaper than Vaillant/Mitsubishi for competitive performance, SCOP up to 4.9) and noise (the EHS Mono HT Quiet is the quietest in its class at 35dB). R290 refrigerant and 70°C flow (great for old radiators) round it out. Trade-offs are the warranty structure and a thinner installer network. (This is about home heating pumps, not tumble dryers — a different product.)
How much does a Samsung heat pump cost?
£7,500–£11,000 installed before grants — cheaper than premium rivals. It’s eligible for the full £7,500 Boiler Upgrade Scheme grant (via an MCS installer), and because Samsung’s price is lower, the grant covers more — net cost as low as £500–£3,500 for a straightforward install. Running ~£850/yr vs ~£1,200 gas. Get three quotes.
How quiet is a Samsung heat pump?
The quietest in its class — 35 dB(A) in Quiet Mode (37–42dB normal), quieter than a fridge and well below most rivals (40–60dB). A real advantage where the unit sits near a bedroom or neighbour, in terraces, or conservation areas. Since noise is a top heat-pump worry, Samsung’s quietness is a genuine selling point.
What are the downsides of Samsung heat pumps?
Mainly the warranty: up to 7 years but only with a Samsung-accredited installer (2 years otherwise), and parts-only. Also a thinner UK installer network (newer entrant, R290-trained installers still building), SCOP not quite the cold-climate top brands, few models above 16kW, and an occasionally glitchy app. Confirm accredited-installer status before booking.
Are Samsung heat pumps good for old houses?
Yes — the EHS Mono HT Quiet’s 70°C flow temperature can heat older, existing radiators effectively, giving a buffer to upgrade rads gradually rather than all at once. That makes Samsung one of the more retrofit-friendly brands for older homes. For newer/well-insulated homes at lower flow temps, the R290 Gen 7 is the more efficient pick.
Do Samsung heat pumps qualify for the £7,500 grant?
Yes — all Samsung EHS models are MCS-certified and eligible for the full £7,500 Boiler Upgrade Scheme grant when installed by an MCS-certified installer in England and Wales. Because Samsung’s installed cost is lower, the fixed grant covers a higher share — making it one of the most grant-efficient choices. See best heat pumps for how it compares.
Superb value and the quietest going — just check the warranty
The bottom line: Samsung’s EHS range is one of the best-value heat pumps in the UK and the quietest in its class at 35dB — a superb combination for budget-conscious or noise-sensitive homes, and brilliant with the £7,500 BUS grant. The 70°C flow suits older homes too. It loses points only on the warranty structure (7 years but accredited-installer-only, parts-only) and a thinner installer network. Confirm accredited installation, and Samsung is a genuinely smart-value choice.

Samsung EHS heat pumps punch well above their price. They’re among the best value on the UK market — significantly cheaper than premium rivals, and exceptionally grant-efficient (net cost as low as £500–£3,500 after the £7,500 BUS grant) — and they’re the quietest in their class at 35 dB(A), a genuine advantage where noise matters. Add a competitive SCOP up to 4.9, eco R290 refrigerant, and a 70°C flow temperature that suits older homes, and Samsung is a genuinely compelling choice that earns a solid 4/5.
The one thing to get right is the warranty: the full 7-year cover requires a Samsung-accredited installer (and is parts-only), so confirm that before booking. The installer network is also thinner than the established boiler brands, so local choice may be more limited outside cities. Get those checked, and Samsung is one of the smartest-value, quietest heat pumps you can buy. The best way to know if it suits your home is an expert survey — a couple of free, no-obligation home surveys from MCS-certified installers will confirm whether Samsung (or a rival) is right for your radiators, budget and site, and what it’ll cost after the grant.
