It’s Monday morning here at Heat Eco Building Services and honestly, looking at the calendar: it’s May 18th 2026 already: you might think heating is the last thing on people’s minds. But if there’s one thing we’ve learned working across Surrey, from the busy streets of Guildford to the quiet corners of Bordon, it’s that the best time to fix your heating is before you actually need it.
Who wants a nasty surprise when the first frost hits in October? Not us, and definitely not our customers. We see the same mistakes over and over again in there homes. Most of them are easy to fix, and they don't just save you a few quid on the bills; they make a massive difference to your carbon footprint too. We’re all trying to do our bit for a greener Surrey, so let’s dive into what you might be doing wrong and how we can get it sorted together.
1. Treating the Thermostat Like a “Turbo” Button
We’ve all been there. You come home to a chilly house in Farnham, you’re shivering, and the first thing you do is crank the thermostat up to 30°C. You think it’ll heat up faster that way, right?
Wrong. Most heating systems: whether it’s a combi-boiler or a modern heat pump: work at a steady rate. Cranking it up doesn’t make the radiators get hot any faster; it just means the system won’t turn off until your house is like a sauna. You end up overshooting the temperature, wasting energy, and then having to open a window because you’re sweating.
The Fix: Aim for steady, moderate temperatures. Set it to 19–21°C and just leave it to do its thing. Better yet, let’s talk about a smart thermostat. It learns how long your house takes to warm up and starts the process early so it's perfect by the time you walk through the door.
2. Heating Rooms Nobody Is Using
If you’ve got a spare bedroom that only gets used when the in-laws visit once a year, why are you heating it to 21 degrees every single day? It’s a classic mistake. We see big houses in Guildford where every single radiator is blasting, even in rooms where the doors stay shut all day.
The Fix: Use your Thermostatic Radiator Valves (TRVs). Those little dials on the side of your radiators aren’t just for decoration. Turn them down to '1' or '2' in rooms you don’t use. If you want to get really fancy, we can install smart TRVs that let you control every room individually from your phone. It’s one of the best ways to cut your gas or electricity consumption without even trying.
3. Ignoring the "Silent Killers" of Efficiency: Sludge and Dust
Your boiler might be running, but is it running well? Over time, the water inside your radiators gets dirty. It turns into this black, nasty sludge that settles at the bottom of your radiators. If the bottom of your radiator feels cold while the top is hot, you’ve got a problem. Your pump has to work twice as hard to push heat around, which wears it out and costs you more.
The Fix: A professional power flush. We bring in our Kamco equipment and give the whole system a proper clean. It’s like giving your heating system a detox.
We’ve seen systems that were barely lukewarm become scorching hot just from a good flush. It keeps everything running smooth and helps you avoid a boiler-installation before you really need one.
4. Blocking Your Radiators with Furniture
We get it: you’ve bought a lovely new sofa and the only place it fits is right against the wall… right in front of the radiator. But here’s the thing: radiators work by circulating air. If you put a massive fabric sofa right in front of one, the sofa gets lovely and toasty, but the rest of the room stays cold. The heat just gets trapped.
The Fix: Give your radiators some breathing room. Even just 6 to 10 inches can make a huge difference in how the air circulates. If you really have to have furniture there, consider reflective radiator foil behind the unit to bounce the heat back into the room rather than letting it soak into the brickwork.
5. Skipping the Annual Health Check
A lot of folks in Bordon and the surrounding areas think that if the heating is coming on, everything is fine. But skipping your annual service is a bit like never changing the oil in your car. Small issues: like a tiny leak or a sensor starting to fail: can turn into a total system breakdown on the coldest day of the year.
The Fix: Get us in once a year. We don't just check if it's working; we check if it’s safe and if it's burning fuel efficiently. A well-maintained boiler uses less gas and lasts years longer. Plus, it keeps your warranty valid, which is a big deal if things do go wrong.
6. Letting the Heat Escape Through "Ghost Holes"
You can have the best heating system in Surrey, but if your house is "leaky," you’re basically burning money to heat the outside air. We’re talking about drafts under doors, gaps around old windows, and even unused chimneys. If you can feel a breeze when you’re sitting on the sofa, your heating is fighting a losing battle.
The Fix: Draught proofing isn't glamorous, but it works. Heavy curtains, letterbox brushes, and even those old-fashioned "sausage" draught excluders for the bottom of doors make a world of difference. If you've got an old fireplace you never use, look into a chimney balloon. It stops the warm air from just floating away.
7. Forgetting the Future: The Eco-Upgrade Gap
The biggest mistake we see these days isn't just about how you use your current heater: it's about not planning for the next one. The world is changing, and Surrey is moving towards greener energy. If your boiler is over 12 years old, you're likely missing out on massive efficiency gains.
The Fix: Start thinking about "Future-Proofing." Have you looked into Air Source Heat Pumps (ASHPs)? Or maybe Solar PV panels with battery storage? We’re doing more and more of these installations in places like Farnham. By generating your own power or using a highly efficient heat pump, you’re not just saving money; you’re protecting yourself against future energy price hikes.
Making It Real: A Greener Surrey Home
We recently worked on a project where the client was complaining about high bills and a cold lounge. After a quick look, we realized they were making four of these mistakes at once! They had a sofa blocking the main radiator, the thermostat was being treated like a light switch, and the system was full of sludge.
We did a power flush, moved the furniture slightly, and installed a smart controller. The result? A warmer house and a bill that dropped by nearly 20% the following month. The client was over the moon, and we were happy to help them make there home a bit more sustainable.
Whether you're looking for a simple plumbing fix or you’re ready to go full "eco" with solar and batteries, we’re here to help. Heat Eco Building Services isn't just about pipes and boilers; it’s about making your home the heart of your life, without it costing the earth.

Quick Checklist for a Toasty Home:
- Check your TRVs: Are they set correctly for each room?
- Bleed your radiators: If there’s air trapped in there, the heat can’t get in.
- Look at your curtains: Closing them at dusk keeps the heat where it belongs.
- Book a service: Don't wait for a breakdown.
- Clear the decks: Move that laundry or furniture away from the heat source.
Taking care of these things now means you can relax knowing your home is efficient and ready for whatever the British weather throws at us. Surrey is a beautiful place to live, and keeping our homes eco-friendly is just one way we can keep it that way for the next generation.
