What Is Gas Fitting?

Gas fitting involves installing, repairing, and maintaining gas appliances and gas pipework. 

All gas work should be completed by a licensed gas fitter to ensure compliance with safety regulations.

Certificates provide proof that installations are safe and compliant.

Gas Appliance Installation

2. Hot Water Systems


Hot Water Cylinders

Traditional hot water cylinders store heated water for household use. 

They are available in low-pressure and mains-pressure models and can be powered by electricity or gas.

Gas Califonts

Gas califonts heat water only when needed, providing continuous hot water without the need for a storage cylinder.

Heat Pump Water Heaters

Heat pump systems use energy from the surrounding air to heat water. 

They are highly energy-efficient and can significantly reduce electricity consumption.

Choosing the Right System

The best hot water solution depends on household size, usage patterns, available energy sources, installation costs, and long-term operating   expenses. Standard hot water cylinders and gas heaters are cheaper short-term options with heat pumps paying off after approximately 5 -7 years.
