A Simple Change That Saves Energy and Boosts Comfort - with Help from Warmflo Heating
At Warmflo Heating, we’re always looking for smart, affordable ways to help our customers get the most from their home heating systems. One of the easiest upgrades you can make is fitting Thermostatic Radiator Valves (TRVs) to your radiators.
These small devices can make a big difference — not just to your comfort, but to your energy bills too.
What Is a TRV and How Does It Work?
A Thermostatic Radiator Valve (TRV) is a temperature-sensitive control that fits onto your radiator. Instead of turning the radiator on or off manually, a TRV automatically regulates the heat output based on the temperature of the room.
Inside the valve is a sensor (usually wax or liquid-based) that expands or contracts as the room heats or cools. This movement adjusts the valve, increasing or reducing the flow of hot water into the radiator.
The result? Each room stays at a steady, comfortable temperature — and you stop wasting energy heating spaces unnecessarily.
Benefits of Installing TRVs in Your Home
✅ Lower Energy Bills
With energy costs continuing to rise, TRVs are a smart move for UK households. By only heating rooms when and where you need it, you reduce energy waste — and that translates to real savings.
✅ Personalised Room Comfort
Want the bedroom cool but the lounge cosy? TRVs make that possible without installing an expensive smart heating system.
✅ Reduced Carbon Footprint
Using less energy means lowering your home’s environmental impact — something more and more of our customers at Warmflo Heating care about
✅ Easy Upgrade
TRVs can be added to most existing radiators without major disruption. It’s a simple, affordable job — and one we handle regularly for homeowners across the UK.
Where Should You Fit TRVs?
We recommend fitting TRVs on radiators in bedrooms, lounges, dining rooms, and spare rooms — anywhere you want more control. However:
Avoid fitting a TRV in the same room as your main thermostat (usually the hallway or living room).
Bathrooms can be tricky, as steam and quick temperature changes can affect the sensor. We’ll help you decide the best approach for those spaces.
Are TRVs Worth It? Absolutely.
TRVs are one of the best-value energy-saving upgrades for any UK home. Combined with regular boiler servicing and a good room thermostat, they help you heat smarter, stay comfortable, and save money all year round.
