How to check if you need a new combi boiler installed before Winter

There’s no great time for your boiler to break down, especially during Winter time, which could leave you facing cold showers and no heating until it gets fixed. Before the cold snap starts, you might want to consider giving your boiler a once over to check it’s in full working order; any breakdowns over the cold months can leave your family well and truly stuck, especially if you have to wait for a professional call out.

What signs should you be looking for?

  • Your house doesn’t seem to get very warm when the heating is on: lots of older boilers are considerably less energy efficient than new ones, running at an average of 70% efficiency, and so over time it may cost you less to upgrade to a better boiler now.

  • Strange noises coming from the boiler: if your boiler is popping or hissing, then it’s definitely worth getting it checked out, as this can be a sign of a larger problem such as uneven water distribution, which will need fixing.

  • Water leaking from the boiler: this one could be potentially serious, as a leak can cause damage to your home and could even escalate into a carbon monoxide leak.

  • Issues with water temperature: if you’re having problems regulating water temperature, or if the hot only works when the heating is on, then it may be time to upgrade.

  • If you’ve had it repaired several times already: paying for repairs on an ageing boiler is a false economy in the long run. If you find yourself paying for call outs on a regular basis, it may be worth getting someone in to price up for a new one.

To keep your boiler in tip-top condition, make sure you also:

Check the boiler pressure

Sometimes a drop in pressure can prevent a combi boiler working, so before the big freeze make sure you check that the pressure is within the correct zone. If you notice that you are having to alter the pressure yourself, then it is time to call in an expert to check for leaks in the system.

Bleed your radiators

If the top of your radiators feel cold when it’s on, then there is likely to be air in the system, so you will need to bleed them. Once you’ve let the air out, this can affect the pressure of the boiler, so you will need to check the levels and potentially top it up.

Of course, no one wants to pay for a new boiler unless absolutely necessary, but if your boiler is not running as well as it used to, or you’re experiencing more and more problems with it, then a new energy efficient boiler now may save you money overall, particularly in light of rising energy costs!
