Precision Heating has announced the launch of two new air source heat pumps with innovative noise reduction technology, the Viessmann Vitocal 200-A and 222-A.

Daikin has announced the launch of the latest addition to its leading Altherma range of air source heat pumps: the ‘best-inclass’ Daikin Altherma 3 H HT. The company said that consumers will appreciate the unit’s high performance, low sound level and unique design.

Viessmann has introduced two new air source heat pumps, the Vitocal 200-A and Vitocal 222-A, which boast innovative noise-reduction technology. Both operate so quietly that they are suitable for densely built-up areas such as terraced housing estates, and both deliver high energy efficiency with low operating costs, according to Viessmann.

Mitsubishi Electric has launched some of the quietest air source heat pumps ever available to offer complete flexibility on where units can be installed – while boosting the unit’s energy efficiency by 7%.

As electricity supply from renewable sources continues to grow, and electricity grids gradually decarbonise as dirtier fossil fuels are phased out, heating homes with electrical technologies like heat pumps starts to make more sense. And in the mild, temperate climate of Britain and Ireland, air source heat pumps are particularly suitable — especially as new build standards of energy efficiency continue to tighten, meaning new homes need less and less energy to achieve comfortable indoor temperatures. But how do air source heat pumps work, what types are there, and how much do they cost to run? Our in-depth guide attempts to answer the key questions.

Homeowner Brendan Murphy started self-building his Cork passive house way back in 2010, long before the standard was trendy, and even chose to completely forgo a water-based heating system. So what did he learn from the experience — and how has the house been performing since?

This large family home in south Dublin proves that big homes don’t need to be cold and draughty, comfortably beating Ireland’s planned nearly zero energy building standard for 2021 — even though it was finished in 2015.

The line-up for the self-contained outdoor units now boasts 5kW, 8.5kW, 11.2kW and 14kW units, to make Ecodan suitable for almost any situation.

Geothermal heating is being specified by everyone from self-builders to developers to local authorities in increasing frequency across Ireland. As a relatively new technology in Ireland, it is crucial that anyone considering a geothermal system knows what they are getting into, to ensure an efficient, reliable heating source.

With over 20 years experience in this field in Ireland, Dr Paul Sikora, Vice Chairman of the Geothermal Association of Ireland explains what issues to be aware of when considering geothermal, from site suitability, to what to look for from suppliers and installers.
