Save on Energy Bills: Harness Smart Technology to Reduce Heating Costs and Repair Your Boiler

Utilize Smart Technology

“Minor adjustments can lead to significant improvements in energy conservation and warmth,” said Sarah Pennells, a consumer finance expert at Royal London.

Firstly, if your boiler or thermostat is equipped with a timer, make use of it.

For enhanced control, consider upgrading to a smart thermostat that connects to the internet. This option lets you manage your thermostat remotely, typically through a mobile app, enabling you to turn the heating on or off when plans change unexpectedly. A smart thermostat acts like a timer for your boiler, allowing you to use the app for scheduling heating and hot water.

Smart thermostats come in various models and offer features like multi-room control, hot water management, and “geofencing” that tracks your presence in and out of the home. Their prices usually range from £60 to £250 depending on the brand.

Bosch Room Thermostat II (£69.99); and Hive Thermostat V4 (£155 B&Q) requires a professional installation, which can typically be arranged through a retailer, though additional fees may apply.

Some energy suppliers offer discounts on smart thermostats from their partnered brands. The Octopus Energy and tado° partnership gives customers up to 50% off on tado° products. The Wireless Smart Thermostat X Starter Kit has been marked down from £159.99 to £112.

<p class="dcr-130mj7b">Research indicates that decreasing the thermostat setting from 22°C to 21°C may save the typical UK household £90 annually.<a href="https://energysavingtrust.org.uk/take-control-your-heating-home/?_gl=1*boqspv*_up*MQ..*_ga*MTQ2OTcwMDExNy4xNzYyMjcwMDYy*_ga_GPYNXFLD7G*czE3NjIyNzAwNjAkbzEkZzEkdDE3NjIyNzA0NzY KajYwJGwwJGgw#jumpto-1" data-link-name="in body link"> Energy Saving Trust</a>. For most, a comfortable indoor temperature lies between 18°C and 21°C.</p>
<p class="dcr-130mj7b">According to <a href="https://www.youtube.com/watch?v=DDZNODZ5qyY" data-link-name="in body link">Citizen Advice</a>, lowering your thermostat can mean saving about 10% on energy bills. However, those who are elderly or have health concerns are advised not to set the temperature below 21°C.</p>

<p class="dcr-130mj7b">Moreover, experts suggest that maintaining a continuous lower temperature consumes more energy than heating intermittently at a slightly higher setting.</p>
<p class="dcr-130mj7b">Setting your heating to switch off 30 minutes before leaving the house or turning in for the night can further decrease your electricity costs.</p>

<h2 id="lower-the-flow" class="dcr-n4qeq9"><strong>Reduce Flow Rate</strong></h2>
<p class="dcr-130mj7b">If using a combi boiler, you can lower the temperature of the flow, which is the water temperature entering the radiator.</p>
<p class="dcr-130mj7b">For those using a system boiler or hot water cylinder, <a href="https://www.edfenergy.com/energywise/lower-flow-temperature-on-combi-boiler" data-link-name="in body link">EDF Energy advises</a> seeking assistance from an engineer for guidance.</p>
<p class="dcr-130mj7b">Typically, boilers have a high flow temperature around 75-80°C. Reducing this to about 60°C might cut your gas bills without noticeably affecting comfort levels.</p>
<p class="dcr-130mj7b">“This approach is particularly beneficial in homes with well-sized radiators and adequate insulation, showing no significant change in comfort,” notes Pennells.</p>
<p class="dcr-130mj7b">The charity Nesta provides an online and interactive <a href="https://www.moneysavingboilerchallenge.com/" data-link-name="in body link">tool</a> to help users adjust their boiler settings. They recommend documenting the boiler's original controls and settings with photos before making changes.</p>

<h2 id="turn-down-radiators" class="dcr-n4qeq9"><strong>Adjust Radiators</strong></h2>
<p class="dcr-130mj7b">If your radiators have a dial controlled by a thermostatic radiator valve (TRV), you can set the temperature individually for each room. TRVs generally have a scale from 0 to 6, with 0 being off and 6 being fully open.</p>

<p class="dcr-130mj7b">The Energy Saving Trust recommends setting your room on the lowest temperature that maintains comfort. You can set 3 or 4 in frequently used rooms and reduce this to 2 or 3 in less-used spaces. They also mention that integrating a TRV into an existing system with a programmer and thermostat could save households around £35 each year.</p>
<p class="dcr-130mj7b">While turning off heating altogether may seem like a good way to save money, experts warn that this could result in mold and dampness, which could incur greater costs and health risks over time.</p>
<p class="dcr-130mj7b">“During the energy crisis, we observed changes in behavior where people started to prioritize heating individuals rather than entire homes,” says project development coordinator Sophie Barr. <a href="https://www.nea.org.uk/get-help/resources/" data-link-name="in body link">National Energy Action</a>. “Our findings indicate that it's more cost-effective to provide heat to the entire area by adjusting radiators in unused rooms to setting 2, thus providing sufficient warmth to deter mold spores that can lead to serious respiratory health issues.”</p>

<h2 id="get-reflectors" class="dcr-n4qeq9"><strong>Install Reflectors</strong></h2>
<p class="dcr-130mj7b">The <a href="https://britishgasenergytrust.org.uk/" data-link-name="in body link">British Gas Energy Trust</a> suggests placing foil behind radiators to reflect heat back into the room. Since approximately 35% of indoor heat escapes through the walls, these reflectors ensure that heat is redirected into the room rather than absorbed by exterior walls, making them particularly effective on uninsulated external walls.</p>
<p class="dcr-130mj7b">Though there may be a small initial expense, they are reasonably priced, simple to install, and durable. They can be purchased in rolls and cut to fit your radiators. They are easy to apply with included adhesive or double-sided tape—first ensuring the radiator is turned off and cool. Screwfix offers rolls of 1.88 square meters for <a href="https://www.screwfix.com/p/essentials-470mm-x-4m-radiator-heat-reflector-foil/88629?tc=JS7" data-link-name="in body link">£7.51</a>, while B&Q has a 5 square meter roll for <a href="https://www.diy.com/departments/diall-radiator-reflector-5m-/1906873_BQ.prd?storeId=1037" data-link-name="in body link">£14.97</a>, and Amazon sells a 15 square meter roll for <a href="https://www.amazon.co.uk/dp/B0CYM442P1?tag=track-ect-uk-2181897-21&amp;linkCode=osi&amp;th=1&amp;ascsubtag=ecSEPr67xojmhks6sn7" data-link-name="in body link">£27.99</a>.</p>
<p class="dcr-130mj7b">To enhance efficiency, bleed your radiators every few months. Ensure the radiator is switched off and cool before inserting the key (<a href="https://www.diy.com/departments/rothenberger-radiator-key-pack-of-2/191173_BQ.prd" data-link-name="in body link">£3.50</a> for a B&Q 2-pack) or a flat-head screwdriver into the bleed valve (often located in the top corner) and turn it counterclockwise. Listen for a hissing sound as air escapes; wait for it to stop, showing a steady flow of water (you can catch it with a cloth), then turn the valve clockwise to close it again.</p>

<p class="dcr-130mj7b">Avoid obstructing radiators with furniture or curtains, especially beneath windows, to distribute heat more evenly throughout the space.</p>

<h2 id="keep-your-boiler-serviced" class="dcr-n4qeq9"><strong>Regular Boiler Maintenance</strong></h2>
<p class="dcr-130mj7b">Routine boiler service enhances efficiency and extends lifespan by addressing minor issues. According to Octopus Energy, neglecting boiler maintenance can lead to up to 10% more energy usage compared to those serviced annually. “Failure to regularly maintain your boiler can significantly affect fuel efficiency and health,” warns Barr.</p>
<p class="dcr-130mj7b">As per Which?, the average cost for a boiler service ranges from £70 to £110.</p>
<p class="dcr-130mj7b">Some energy providers include this service in their annual coverage plans, such as British Gas, which features it in their <a href="https://www.britishgas.co.uk/cover/boiler-and-heating.html" data-link-name="in body link">home care</a> options starting at £19 per month. However, a boiler care plan might not be suitable for every consumer. Which? recommends considering if your monthly contributions may exceed the costs of the annual service or repairs. Ensure you have savings to cover the full service fee as needed.</p>
<p class="dcr-130mj7b">For renters, it is the landlord’s obligation to arrange for annual boiler inspections and certifications. “Annual maintenance is mandatory for all rental properties,” says Barr. "For homes with gas boilers, only a gas safety engineer should perform this work, and an Oftec certified engineer should handle oil boilers. Annual boiler maintenance guarantees that your system operates efficiently and prevents carbon monoxide leaks in your home."</p>
