Heat load surveys and system design in Ystradgynlais
Wet South Wales winters make a heat pump's quiet, even heating and dehumidifying mode useful well beyond summer. Every Ystradgynlais quote starts with a room-by-room survey rather than a guess from floor area.
No two rooms in Ystradgynlais gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Our Powys coverage takes in Ystradgynlais, about 55 miles from Newtown. That includes the SA9 postcode district.

Planning and permissions
In Wales, outdoor units of up to 1.5 m³ that meet MCS 020a noise limits are usually permitted development on houses; listed buildings need consent, and in conservation areas a unit cannot go on a wall or roof facing a road.
The survey
The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote. At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote.
