Conservatory air conditioning in Harlow

Why is a conservatory so hard to keep comfortable?

Sun pours in through glass, heat pours out through it, and nothing in the structure stores warmth to even things out. The Writtle climate station, 14 miles from Harlow, averages about 1,644 hours of sunshine a year and around 49 days of air frost, and a conservatory feels every one of them. Garden rooms do the same on a smaller scale, thanks to thin walls and big glazed doors.

So a plug-in heater and an open door never quite work. Here too, air-to-air heating pays best, because the usual alternative runs at full electricity prices.

What size unit does a conservatory need?

Probably bigger than a chart suggests, since charts assume an ordinary room. Facing south or west pushes the figure up. So does a glass roof, and doors to the house left open. Blinds bring it down. We would sooner measure and calculate than read a number off a table, and the size guide lists what to look at.

Where can the indoor unit go?

Solid wall is scarce, and glazing will not hold a wall unit. The house wall is the usual answer. Failing that, a low floor-standing model can sit in front of a dwarf wall. Fixing to a frame is only an option where the structure and the maker both allow it. Whichever you choose, the outdoor unit can usually be close by, so the route stays short.

Does a garden room have enough power?

Often not, because many garden offices are fed by one cable sized for sockets and lights. That gets checked before anything else, and a new circuit out to the building is notifiable under Part P. If you have not built yet, note that in Mark Hall North the Article 4 direction means a rear outbuilding itself needs a planning application.
