Introducing the Solar Block Ultra, an all-in-one solution for your domestic hot water and underfloor heating needs



The new Solar Block Ultra is a combined domestic hot water and underfloor/central heating unit. It uses inverters which makes it highly efficient and will continue to operate efficiently when the central heating is turned off in summer. Because it is a combined unit it is easy to install and requires less plumbing, and you don’t need a separate domestic hot water system. It has a heat exchanger for the underfloor/central heating and a 200 litre stainless steel hot water cylinder for domestic use.


This unit comes with multiple solar thermodynamic panels and is 30% more efficient than a standard air to water heat pump because of the solar gain from the panels. It has a maximum heating capacity of 18.7kw.
