Evidence base: How air source heat pumps fare in canny retrofits

Air source heat pumps are rapidly becoming one of the dominant technologies in sustainable building, but how well do they perform in real world conditions? Can they be part of the solution to retrofitting homes, given the challenges in making existing homes suitable for low energy heating? A rare monitoring study on a pioneering retrofit scheme offers encouraging signs.

Athlone scheme hits NZEB with Firebird heat pumps

Leading Irish heating system manufacturer Firebird has recently completed a full heating installation at a scheme of 16 new build dwellings in Athlone, Co Westmeath, all designed to achieve the NZEB standard and an A2 BER.

Viessmann launches new compact heat pump

Viessmann has introduced the new Vitocal 100-A air source heat pump, the most compact and affordable model in its range. Designed for ease of installation in the standard British heating system – and therefore ideal for the replacement of gas and oil boilers – the monobloc unit’s tight dimensions are perfect for homes where space is at a premium. Its A+++ rated energy efficiency will benefit end-users with low running costs, Viessmann said.

Daikin launches Altherma 3 high-temp heat pump

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 launch new ultraquiet air source heat pumps

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.

The PH+ guide to air source heat pumps

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.

Life in an air-heated passive house - Five years on

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?

Going Underground

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.
