If you’ve been wondering whether a smart thermostat is really worth it — or just another tech gimmick — you’re not alone. We get asked this all the time when we’re fitting boilers or upgrading heating systems in and around Exeter.
So, here’s a straight-talking guide: what smart thermostats actually do, who benefits most, and whether it’s the right fit for your home.
What Is a Smart Thermostat?
A smart thermostat connects to your heating system and your Wi-Fi, letting you control your heating through an app on your phone — wherever you are. Some also learn your habits and adjust automatically to help save energy.
The most popular brands we fit in the UK include:
Nest
Hive
Tado
Drayton
They all do slightly different things, but the goal is the same: more control, more comfort, and potentially lower bills.
What Are the Benefits?
1. Control from Anywhere
Left the heating on while you’re out? Turn it off from your phone. Want to warm up the house before you get home? Easy.
This is one of the biggest reasons people around Exeter ask us to fit smart thermostats — especially in the winter months.
2. Smarter Schedules = Real Savings
Many smart thermostats learn your routines or allow you to create detailed schedules — down to the minute.
Combine that with features like geofencing (turning heating off when you leave home) and weather compensation, and you start to see real savings.
Typical annual savings:
Estimates vary, but most manufacturers suggest £100–£150 per year — depending on usage and property type.
3. Zoned Heating Options
Some systems (like Tado or Wiser) allow individual room control. That means you can heat only the rooms you’re using — ideal for larger homes or hybrid workers using a home office.
We’ve fitted these in a number of homes where the layout makes it hard to heat evenly — and the difference it makes is massive.
4. Eco-Friendly and Future-Proof
If you’re thinking long-term — heat pumps, energy monitoring, smart homes — a smart thermostat is a great first step. Some models integrate with solar PV, EV chargers, and more.
Plus, reducing energy use isn’t just good for your wallet. It’s good for the planet too.
Can You Install One Yourself?
Some are DIY-friendly, but many smart thermostats need a professional install — especially if your boiler wiring is older or you’re connecting it to underfloor heating or zoned systems.
We’ve been out to more than a few jobs where customers tried to fit one and ended up with no heating at all… not ideal during a Devon winter.
If in doubt, give us a call and we’ll let you know whether it’s a quick fit or something that needs rewiring.
Things to Watch Out For
Compatibility: Not all smart thermostats work with every boiler — especially older models.
Internet required: No Wi-Fi = no smart features.
Upfront cost: Expect to pay £150–£250 for the thermostat, plus install.
Overcomplication: Some systems are too clever for their own good — if you don’t need zoned control or app automation, a simpler thermostat might do the job.
Is a Smart Thermostat Worth It?
In our opinion? Yes — for most households.
If you:
Want more control over your heating
Have a regular routine or are often out during the day
Want to reduce energy use without sacrificing comfort
…then a smart thermostat is a solid investment.
It won’t solve every heating issue, but used right, it can save money, increase comfort, and give you total control — all from your phone.
Final Thoughts from EPM
Smart thermostats are no longer just a “nice to have” — they’re becoming the standard. Whether you’re upgrading your boiler or just want to cut bills, they’re well worth considering.
