The Benefits of a new stainless steel hot water cylinder

Using your new Hot water cylinder replacement during the summer months

Is it cheaper to heat my home with gas or electricity?

We get asked this question on a regular basis – and on the face of it, it has a very simple answer.

To buy one unit of mains gas (measured in kWh) you will pay about 5 cents / kWh. Conversely, one unit of electricity from the mains (also measure in kWh) will cost you about 17 cents/kWh. This means that gas is about 3-4 times cheaper than electricity per kWh.

Therefore it makes sense to use your gas boiler to heat water via a hot water cylinder.

Cylinder coil corroded due to hard water damage

Hard water over time can have a negative effect on how efficient your water cylinder performs.

Unlike the treated water in your rads, fresh water is constantly passing through the cylinder and because it’s heated up it acts in the same way a kettle would and attracts the lime in the hard water.

Stainless steel cylinders are less reactive to corrosion than copper cylinders.

Because of the nature of stainless steel, it doesn’t react in the same way copper does and this makes it an ideal replacement. As a result your new cylinder will heat up quicker meaning less gas usage.
