Retrofit, warming to heat pumps: Cut your utility bills with home retrofits

If your home is insulated to the right level and has low heat loss (HLI) with managed ventilation, it may be ready for a whole, new sustainable heating system.
The SEAI in their effort to transform the way we use energy, advise us to: assess our needs, insulate, and then and only then, to add renewable energy technologies (heat pumps, solar water heating panels or solar photovoltaic panels). Delivering a snug box that holds heat inside our homes, insulation is first, last and always in any serious energy renovation.
