There are a few different options when choosing gas hot water for your home. Hopefully the following will help in making your selection but please get in touch if you have any questions.

Inside or Outside

Gas hot water systems can be placed inside or outside the house, outside is usually the preferred choice due to space savings inside. Internal options are usually more expensive as they require a flue to disperse the products of combustion.

Storage or Continuous?

Storage hot water systems heat and then keep a body of water warm in the same way electric ones do – except using gas which means using a much cheaper fuel source. They come in a variety of sizes to suit your households requirements, the name of the unit usually signifies the litre capacity of the unit.

Continuous hot water systems have low running costs and are often known as on demand or tankless water heaters. Unlike a traditional hot water cylinder which has to maintain a constant temperature throughout the day gas water heaters only heat the water as and when it is needed. These continuous flow systems provide instant hot water and plenty of it! No more cold showers for the last one out of bed in the morning! We install a range of continuous flow gas hot water systems from reputable brands such as Rinnai and Paloma. There is no storage of hot water – no keeping water warm until required – just endless hot water when required.
Small and discreet and are usually placed outside for maximum space savings inside.

How do they work?

As soon as you turn the hot tap the system ignites heating the water to a pre-defined temperature. This happens via a heat exchanger that transfer heat to the water from the gas-fired burner.
