Heatrae Sadia Amptec

Amptec electric flow boilers are sized to efficiently meet a wide range of different needs, and can be installed singly, or as multiple units, making them suitable for properties from mobile homes up to large family houses. The Amptec range includes an 11kW model designed to match the rating of existing domestic electrical power supplies and models suitable for conventional radiator heating systems or for underfloor heating applications.

Amptec boilers can be installed to provide central heating and domestic hot water in conjunction with an indirect hot water storage cylinder or if preferred, to provide heating only with domestic hot water being supplied by a direct hot water storage cylinder. In rented property, gas appliances must have annual maintenance checks by law. The Amptec electric flow boiler offers a low maintenance alternative.
