Trianco, has supplied Activair indoor air source heat pumps for a £100,000 development programme in Scotland in partnership with principal contractor, the Procast Group.
The joint trial by Procast and Trianco, on six flats managed by Argyll Community Housing Association (ACHA), serves to test and examine an alternative to communal heating and district heat networks.
The trial project is a first for Scotland as contractor Procast looks for a highly efficient air source heat pump (ASHP) unit that would be suitable for installing in the most difficult to treat flats and tenements throughout the UK.
Peter Beighton, Managing Director of Trianco explains, “This trial is a huge step forward in bringing innovation and practicality together. It is hoped that the new installations, which are far more compact than a typical ASHP, which sits outside of a property, should improve energy efficiency, provide tenants with savings and lead to better insulated homes, as well as being better for the planet. These heat pumps fit into the kitchen just like an additional boiler would. Now completed, the project will have a hugely positive impact on living conditions for tenants as well as help to reduce their energy bills.
Derek Innes, Owner and Managing Director of Procast Group, said: "Innovation and technology is a huge part of what we do at Procast Group and this project is a shining example of that.
"Working with Trianco and Argyll Community Housing Association, we’re intrigued to see how Trianco's indoor ASHPs can have a positive impact on the lives of people in the community on Glebe Street.
"The project also highlights yet another important piece of work from Procast Group to help improve the housing stock on Scotland’s islands and in our most rural communities."
Peter, said: “Our Indoor Heat Pumps are ideal for apartments and properties without the space outside for a traditional heat pump or where planning rules would restrict an outdoor unit. The heat pump is connected to outside with two air ducts, one to draw air in and the other to expel the air. This project is really exciting for us and will hopefully lead to further projects partnering with Procast”.
The units are available in 5 or 7kw outputs and can be purchased as a solo heat pump (which can be connected to a third-party cylinder for hot water) or as either a vertical or horizontal configuration with combined heat pump and domestic hot water cylinder. There are also flexible ducting options using either rectangular or circular ducting which can be connected to either the left, right or rear of the heat pump.
Trianco is committed to developing innovative renewable heating solutions.
