48 West George St, Glasgow, G2 1BP
Supplying A-rated condensing combination boilers directly to Glasgow homeowners at trade wholesale prices. Instant, unlimited hot water straight from the mains without cumbersome loft tanks or airing cupboard cylinders.
A combination boiler integrates two distinct heating functions into a single wall-mounted appliance: a high-efficiency central heating circuit and an instantaneous domestic hot water heater.
Unlike traditional systems that pre-heat 150 litres of water in a cylinder and let it slowly cool down, a combi only burns gas when you open a hot tap, drastically reducing wasted energy and lowering monthly utility bills.
Modern compact combis (like the Worcester Bosch Greenstar 4000 or Ideal Logic+) measure just 700mm × 395mm × 278mm, allowing them to tuck seamlessly inside standard 300mm British kitchen wall cupboards.
Because combis connect directly to your incoming cold mains, hot water is delivered to showers and mixer taps at mains pressure, completely removing the need for noisy electric shower pumps.
Combi boilers are rated by their hot water kilowatt (kW) output. In Glasgow tenements with high 3-metre ceilings, proper output calculation ensures adequate room comfort and rapid tap fill rates.
