Heating & ventilation

Warmer Water, Lower Running Costs

Heating that stretches an outdoor pool's season, and climate control that keeps an indoor pool hall comfortable, dry and cheaper to run.

Overview

No Single System Suits Every Pool

Outdoors, the right heating depends on the pool's size, how exposed it is, how often you swim and how long you want the season to last. We compare the options on what they cost to fit, what they cost to run and how they cope with British weather.

Indoors, heating the water is only half of it. A pool hall needs heating, dehumidifying and fresh air working together, or the moisture ends up on the windows, walls and ceiling. We design the whole system around your building, its glazing and how you'll use it.

Heating Options We Fit

  • 01

    Air-Source Heat Pumps

    Usually the most efficient way to keep water warm, especially with a good cover. Output drops as the air gets colder.

  • 02

    Gas & Oil Boilers

    The fastest way to heat up, and an option where a boiler is already in place. Running costs need weighing up.

  • 03

    Electric & Solar

    Electric heaters suit smaller pools and spas. Solar panels can top up the heating and cut energy use.

  • 04

    Indoor Climate Control

    Dehumidifying, air heating, fresh air and heat recovery, either in one integrated unit or as separate parts.

Common Questions

What's the best way to heat an outdoor pool?

It depends on the pool, how much you use it and how long you want the season to last. Air-source heat pumps are usually the most efficient for keeping water warm, especially with a good cover. Gas or oil boilers heat up fastest, electric heaters suit smaller pools and spas, and solar can top up the heating.

How do you stop condensation in an indoor pool hall?

With a climate-control system designed for pool halls, not standard house ventilation. The air is usually kept 1 to 2°C warmer than the water and humidity around 50 to 60%, with warm air directed at glazing and outside walls. Heat recovery stops most of that warmth going to waste.

Do I need a pool cover?

A good cover keeps the heat in, cuts evaporation and chemical use, and keeps leaves out. Automatic slatted covers open and close at the touch of a button. If safety is the reason, choose a cover certified for it: not every cover is, and none replaces barriers or supervision.
