Heating & Ventilation

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.

Vectaire

Vectaire’ s MVHRs – vertical and horizontal – are all low energy products with EC motors and ensure optimum ventilation and air quality together with low noise levels, running costs and excellent SFP ratings.
They can now be commissioned via an LCD screen. The upright whole house heat recovery units – the Midis and the Maxis- offer the option of either an integral LCD or a remote LCD commissioning unit, whilst the in-line EVO250 and Mini can be commissioned using the remote unit.
Thus, the commissioning engineer can easily adjust detailed unit functions including, for example, the trickle, purge and boost speeds for each motor, the length of the boost speed over-run time, the time delay before the boost speed kicks in, holiday mode and nighttime boost. These products are SAP PCDB Listed and manufactured in our own factory in the UK.

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.
