Benefits of Having an Electric Boiler

The first and biggest advantage of having an electric boiler is rather obvious but to fully realize it, first we have to talk about traditional gas boilers. In order for those appliances to electic boiler running cost work, they have to burn gas. Electric heating systems do not need to do that. This means two things: first, likely lowered bills which is obviously often the biggest reason for a purchase like that. Second, by using electric devices instead of those that burns fossil fuels, you make your home more environmentally friendly. This is an important factor for many. The electric method simply allows the device to deliver the heating energy in a more efficient way, hence making it more environmentally friendly. A central heating boiler is simply an amazing alternative to gas powered variants, and any boiler installer or heating professional will confirm this for you. If you are looking to replace your old boiler, go electric.

Reduced installation costs

Relying on electric boilers for hot water is one of the best ideas you can have if you currently have a gas powered appliance. We have already talked about the efficiency gap and the eco-friendly nature of those devices, now let’s discuss another factor that could very well come into play if you are building a new home or redoing one. Installation! The installation of an electric device can also be a lot cheaper. Think about it, with a gas boiler you need a gas pipe and often a chimney, needless to say that with a small electric boiler that will be an alternative to gas central heating you don’t need any of those.

Noise reduction

Another aspect we cannot overlook is the reduced noise. Electric heating systems are generally much quieter than their gas powered cousins and that is especially true to dome of the newer models. If you are living in a relatively small house or a big one with certain acoustic qualities, noise can actually be a rather big problem. Some of us cannot tolerate any loud noises while trying to sleep and a noisy boiler can be a big distraction. With an electric version this will no longer be a problem for you.

Less maintenance

Any decent electric boiler company will vouch for the fact that these appliances require much less maintenance. Traditional gas or oil boilers are very needy when it comes to maintenance and since they are inherently more dangerous as well, you have to constantly check them for possible flaws that could lead to a malfunction and a possibly even bigger problem.

Electric wet central heating systems will demand a lot less from you which is ultimately something you want with a home appliance. You want a boiler that can put out an optimal performance without you having to worry about it, much less constantly maintaining it. Not to mention your – likely – much reduced boiler running costs. A small electric boiler can do wonders for you and your bills.

Types of hot water systems

Thermaflow boiler

A Thermaflow boiler offers various advantages even compared to regular electric boilers, never mind traditional gas or oil variants. For starters, these appliances will store the energy for you, using it to heat the water later. This saves you money. The other major advantage is of course the technology itself which incorporates a thermal solar, making the whole system even more efficient. What this all means? The device will heat your water by using heat energy in the most efficient way possible. This is a combination that’s very tough to beat. These appliances could save you 40% energy compared to the flow boiler. That’s a major difference that will save you money.
