Sime ’ s unique integrated heat pump and boiler brings Revolution to the renewables sector !

The Murelle Revolution 30 is the first integrated boiler and heat pump in a single cased product .
Using an ErP A ++ 30 kW Murelle boiler and completely sealed 4kW output heat pump , the Murelle Revolution 30 is a single compact unit that can be installed by any registered Gas Safe installer in a single installation process , without requiring an additional F-gasregistered installer to be present .
The unique Murelle Revolution 30 should be installed inside and hung on the wall like a conventional boiler .
The Revolution provides heat and hot water , achieving an average seasonal heating performance of 134 %, granting A ++ energy efficiency , according to the ErP Ecodesign Regulation .

Gaia ’ s underfloor heating can benefit everyone

When specifying heating in domestic properties , underfloor heating ( UFH ) is increasingly seen as the system that offers the levels of energy efficiency and comfort required . In design terms , UFH provides the added benefit that , unlike radiators , it does not have an impact on interior aesthetics and layouts .
This leaves just one perplexing issue ; whether to opt for a wet ( hydronic ) system or an electric system .
Both offer advantages and disadvantages . Wet UFH systems circulate water
heated to around 45-50 º C through loops of pipe laid into the screed of solid floors or the joists of suspended timber floors .
The low temperature of the water used makes these systems energy efficient and ideally suited to use with air or ground source heat pumps or district heating systems . Electric systems use a continuous cable , either laid within the screed or supplied as a mat which is laid above the subfloor .

Some 180 Marmox Thermoblocks have been supplied to a regional builder for the construction of a high specification home near Harrogate , with their unique combination of insulating and load-carrying properties being used to tackle cold bridging where the two storeys above ground meet the basement structure which contains a swimming pool and other recreation areas .
The five bedroom property has been built by Dobson Construction with a beam and block ground floor being supported off the in-situ concrete basement walls .
The partially filled external wall of dense concrete blockwork , with an outer leaf of quarried stone , was then raised on the continuous course of Thermoblocks .
