Do I need a new system?
Firstly, before we run through the different types of central heating, it’s worth asking whether you actually need a new system. Obviously, if you’re undergoing a building project or major renovation, then it’s likely you do. However, if you’ve got a system that’s fairly new but is underperforming, it might just need an upgrade rather than a complete replacement.
Sometimes a system just needs a little TLC to help it function better. For instance, if you have a gas central heating system, a boiler service and power flush might be all you need to improve warmth and efficiency. Or you may simply need to replace or reposition a few of your radiators or heaters. This might be more cost-effective than buying and installing a whole new system.
What are my choices?
If you do need a new central heating system, what are your choices? Let’s start with gas, as these systems are tried and tested and are what many of us are familiar with.
As a fuel, gas is cheaper than electricity. So, it can be the most cost-effective in the long term and the efficiency of gas boilers has increased considerably over recent years. There are plenty of Gas Safe engineers, up and down the country, so you should have no problem finding someone to install the system for you. However, you are committing yourself to using fossil fuel and you will need to get your boiler serviced annually to ensure it stays safe and efficient.
There are three different types of gas central heating systems. Conventional and system boilers employ a hot water tank, which means you can boost your home’s efficiency by heating your water with solar thermal panels. System boilers don’t need a cold water tank, so take up less space than conventional systems and do tend to warm radiators a bit quicker.
Gas combi boilers provide both heating and hot water. As they don’t need a hot or cold water tank, this can be most convenient and space-saving option for some people.
Alternatives to gas
To have a gas central heating system you do need to live in an area that’s supplied by the gas grid. If you live in a rural area where there’s no mains gas, you might need to consider an oil-fired system instead. However, you’ll need outside space for an oil storage tank and the installation must comply with building regulations. You’ll also need to monitor your consumption to make sure you book a delivery in before you run out of fuel. So, it’s worth installing a digital or smart monitoring system to make this easy.
The other alternative to gas is electric central heating. This can come in the form of an electric boiler and radiators, or panel heaters. Electric systems can be the best option for small, well-insulated properties. Although they’re typically more expensive to run, modern systems are efficient and can be combined with solar panels to bring your running costs down and increase your eco-friendliness. Unlike gas, electric boilers don’t need a flue, so can be fitted on any wall and do operate quietly. In a similar manner to gas central heating, panel heaters and night storage heaters come with timers and thermostatic controls, so they’re easy to programme and don’t need a boiler. If you want to save even more space or heat rooms more consistently, you could install underfloor heating instead of panels.
If sustainability is a priority, then you might consider a heat pump instead. A heat pump can be used with radiators or underfloor heating. It would future-proof your home and could raise its value – especially if it’s combined with solar panels. Although it involves a much higher installation cost, a heat pump could be the best way to control your energy bills long term.
How to choose a new central heating system
So, how do you choose a new central heating system from these options? Well, the first thing to check is whether gas is available in your area. The second thing to consider is what systems are suitable for your home. For instance, an oil-fired system or heat pump would require some outside space. Then there’s the space inside. If your rooms are small, would a gas combi boiler or electric underfloor heating – possibly powered by solar panels or a heat pump – help you to save space?
Thirdly, are you planning to install any eco-friendly measures such as solar panels, solar thermal panels or a heat pump in the future? This might make a conventional gas boiler or an electric system the better option.
Electric and heat pump systems are best suited to homes that are well insulated to ensure they work well and don’t cost you too much. So, you also need to consider how efficient your home is or whether you’re willing to make some improvements. It’s also worth considering whether you’re planning to install secondary heating, such as log burners, to help keep your home warm and control bills?
