Retrofit Low Energy Floor Heating
Until now the benefits of an in-floor central heating system, especially when paired with heat pump technology, have only been available in new home builds. Warm & Cool is excited to announce that in-floor heating can now be retrofitted into existing homes - both old and new.The retrofitting system offered by Warm & Cool is well proven, being used extensively throughout Europe and has many advantages over hot air heating systems:
- Consumes up to 30% less energy than hot air heating systems in a house with a 2.4m stud height (even more in the case of larger stud heights)
- In-floor systems heat primarily the objects in the home like a light shining on them (floor, walls, furniture and you) not the air around objects
- The heat from a centrally heated floor is typically a more comfortable heat than that achieved by hot air systems due to a better maintenance of natural humidity levels.
- Advantage of heated floor better ventilation with less net energy loss.
- Low water running temperatures (approx 38°C) combined with the extraordinary efficiency of air to water heat pumps (in the order of 400%) results in much lower energy usage and cost. So $1 buys around $4 heat, plus 30% less energy is needed to keep a given 2.4m stud space warm 24/7.
The Retrofitting Process
- The existing floor covering is first removed
- Next a closed cell foam layer (approx 38mm thick) is applied to the existing slab
- Metal trays are then placed on top of the foam and heating pipes are laid within furrows in the trays
- Finally, cement board (for carpeting or tiling) is placed on top of the metal trays
This Dunedin home, situated on a sloping peninsula section, has half concrete half particle board flooring.
Warm and Cool installed a heat pump powered retrofit radiant floor system over the existing flooring, transforming the home into a much warmer and inviting environment over the cold Otago winter months.
