Frequently asked questions
How much does a Samsung EHS heat pump cost in Wales?
£8,000 to £12,000 installed before the grant, or £500 to £4,500 after a £7,500 grant. These are PumpSwap's indicative 2026 prices; your installer's survey sets the real figure.
Can I get the grant on a Samsung EHS heat pump in Wales?
Yes, if your home qualifies: the Boiler Upgrade Scheme is not tied to a brand, as long as the installer is MCS-certified. It comes straight off the quote.
What would a Samsung EHS heat pump cost to run in Wales?
Roughly £690 a year for the EHS Mono HT Quiet 8kW to deliver 10,000 kWh of heat at 26.55p per kWh (Ofgem price cap for Southern Wales, 1 October to 31 December 2026). That assumes a 45°C design flow temperature, estimated from its MCS-certified SCOPs of 4.46 at 35°C and 3.22 at 55°C. A lower flow temperature, with bigger radiators or underfloor heating, costs less to run.
