The Essential Winter Checklist for Your Heating and Plumbing

As the evenings draw in and the temperature starts to drop, your heating and plumbing are about to do their hardest work of the year. Boilers that have sat quietly all summer are suddenly running for hours a day, pipes are exposed to freezing nights, and any small problem you have been putting off tends to show itself at the worst possible moment.

The good news is that a little preparation goes a long way. Taking the time to prepare your home for winter now can help you avoid unexpected repair bills, reduce the risk of a breakdown when you need your heating most, and even bring your energy bills down.

This winter heating checklist and winter plumbing checklist covers the key areas to look at, from your boiler and radiators to your pipes and gas appliances, along with some simple home winter tips that could save you money over the colder months.

Start with a Boiler Service Before Winter

Your boiler is the heart of your heating system, so it makes sense to start here. Booking a boiler service before winter is one of the most effective ways to avoid a cold and costly surprise in the middle of January.

During a service, a Gas Safe registered engineer will inspect your boiler, check it is burning gas safely and efficiently, clean key components and look for signs of wear. Small issues such as a worn seal, a blocked condensate pipe or a struggling pump can often be picked up early, when they are quicker and cheaper to fix.

There are financial benefits too. A boiler that runs efficiently uses less gas to heat your home, which helps keep your bills under control. Most manufacturers also require an annual service to keep the warranty valid, so skipping it could leave you paying for repairs that would otherwise have been covered.

Timing matters as well. Demand for heating engineers climbs through autumn, and once the first cold snap arrives, diaries fill up quickly. Booking early means you can choose a time that suits you. It is also worth switching your heating on for a short while before the cold weather sets in. If the boiler struggles to fire up, makes unusual noises or shows a fault code, you will know while there is still time to get it looked at.

Give Your Radiators Some Attention

Once the boiler is sorted, turn your attention to the radiators. If a radiator is warm at the bottom but cold at the top, air has usually become trapped inside. That air stops hot water circulating properly, so the room takes longer to warm up and your boiler works harder than it needs to.

Bleeding your radiators is a simple job that most homeowners can do themselves:

1. Turn your heating off and let the radiators cool down.
2. Use a radiator key to slowly open the bleed valve at the top corner of the radiator.
3. Hold a cloth underneath to catch any drips. You will hear a hissing sound as the air escapes.
4. Close the valve as soon as water starts to come out.
5. Check your boiler pressure afterwards, as bleeding radiators can cause it to drop.

If a radiator is cold at the bottom but warm at the top, the cause is more likely to be sludge. Over time, rust and debris collect inside the system and settle in the radiators, reducing the heat they give out. A system flush and a chemical inhibitor can help, and this is a job best left to a heating engineer.

It is also worth noticing whether some rooms heat up much faster than others. If so, the system may need balancing so hot water is shared evenly around the house. Finally, keep furniture and long curtains away from radiators where you can, so the heat warms the room rather than the back of the sofa.

Protect Your Pipes from Freezing

Frozen pipes are one of the most common and most expensive winter plumbing problems. When water freezes it expands, and that pressure can split a pipe. Often you will not notice anything until the ice thaws and water starts leaking into your ceilings, walls or floors.

A few simple steps can greatly reduce the risk:

• Lag exposed pipes. Pipes in lofts, garages, under floors and along external walls are the most vulnerable. Foam pipe lagging is inexpensive, widely available and easy to fit.
• Insulate your water tank. If you have a cold water tank in the loft, make sure it has a proper insulating jacket.
• Look after outside taps. Turn off the indoor isolation valve for any outdoor tap, open the tap to drain the remaining water and fit an insulated cover.
• Fix drips and leaks now. A dripping tap or slow leak is more likely to freeze and cause damage, and it wastes water in the meantime.
• Keep some heat on when you are away. Set your heating to a low temperature or use the frost setting on your boiler so the property never gets cold enough for pipes to freeze.

If you have a condensing boiler, keep an eye on the condensate pipe that runs outside. It is particularly prone to freezing, and when it does, the boiler will usually shut down and display a fault code. Lagging this pipe is a small job that can prevent one of the most common winter breakdowns.

Stay on Top of Gas Safety

With windows closed and the heating running for longer, winter is when gas safety matters most. Faulty or poorly maintained gas appliances can produce carbon monoxide, a gas you cannot see, smell or taste.

Make sure you have a working carbon monoxide alarm in any room with a gas appliance, such as a boiler, gas fire or cooker, and test it regularly. Common symptoms of carbon monoxide poisoning include headaches, dizziness, nausea and tiredness, and they often ease when you leave the house.

Watch for warning signs on your appliances too. A lazy yellow or orange flame instead of a crisp blue one, sooty marks around an appliance or excess condensation in the room can all point to a problem that needs checking by a Gas Safe registered engineer. If you are a landlord, an annual gas safety check is a legal requirement.

If you ever smell gas, turn off the supply at the meter if it is safe to do so, open the windows, avoid using electrical switches and call the National Gas Emergency Service on 0800 111 999.

Heating Tips to Save Energy This Winter

Preparing your home for winter is not only about avoiding problems. It is also a chance to make your heating work smarter, so you spend less to stay warm. These heating tips to save energy are easy to put into practice:

• Turn your thermostat down by one degree. Many people find somewhere between 18°C and 21°C comfortable, and lowering your setting by just one degree can make a noticeable difference to your annual heating bill.
• Use your timer. There is no need to heat an empty home. Set your heating to come on shortly before you wake up or get home, and to switch off when you leave or go to bed.
• Make the most of your radiator valves. Thermostatic radiator valves (TRVs) let you set a different temperature in each room, so spare bedrooms can stay cooler while the rooms you use most stay cosy.
• Consider a smart thermostat. Smart controls let you adjust your heating from your phone and help you avoid heating the house when nobody is in.
• Check your boiler flow temperature. On many combi boilers, the water sent to the radiators is hotter than it needs to be. Lowering it can help a condensing boiler run more efficiently, and your engineer can advise on the right setting during your service.
• Stop draughts. Gaps around doors, windows, letterboxes and floorboards let warm air escape. Draught excluders and sealing strips are cheap and simple ways to keep the heat in.

On their own, these changes may seem small. Together, they can make your home feel warmer while keeping your energy use and costs down.

Be Ready if Something Goes Wrong

Even with the best preparation, problems can still happen. Knowing what to do in the first few minutes can limit both the damage and the cost.

Start by finding your stopcock. This is the valve that shuts off the mains water supply to your home, and it is often under the kitchen sink, in a downstairs cupboard or where the water pipe enters the property. Check that it turns easily, because a stopcock that has seized is no help in an emergency.

Get to know your boiler pressure gauge as well. For most systems, the pressure should sit at around 1 to 1.5 bar when the heating is off. If it keeps dropping below that, there may be a leak in the system that needs investigating.

Finally, keep the details of a local plumbing and heating engineer somewhere easy to find. If a pipe bursts or your boiler stops working on a freezing night, you will not want to be searching for help at the last minute.
