Strom Elite 14.4kW Single-Phase Electric Combi Boiler, 171RT

This Strom Elite single-phase electric combi boiler supplies up to 14.4kW to central heating and domestic hot water. Screwfix lists a 7L/min hot water flow rate and a serpentine heating element. It can serve a compatible wet underfloor heating system and needs no combustion flue or separate hot water cylinder. The Elite listing carries a ten-year manufacturer guarantee subject to registration terms. Screwfix marks it unsuitable for baths; confirm the electrical supply and expected water use. The 171RT Screwfix code denotes the 14.4kW Elite listing rather than the lower-priced standard SBSP15C model. The nominal hot water output does not guarantee the quoted flow in every property because inlet water temperature and plumbing conditions can vary. Its ten-year guarantee requires meeting the manufacturer’s registration terms. Check the wet heating emitters and normal peak hot water use before choosing this unit.
