Immersion heater timer fitted and programmed to your routine. Hot water when you need it, money saved when you don't. Simple, effective, pays for itself in a couple of months.
Stop Paying to Heat Water You're Not Using
Here's the thing: your immersion heater costs about £2 per day to run continuously. That's £60 a month. £730 a year. For hot water you only actually use for maybe 4 hours a day total.
A timer changes that. Heat water when you need it, off the rest of the time.
💡 Pro tip: Most households need hot water twice daily - mornings for showers, evenings for washing up. That's 4 hours of heating vs 24 hours. The maths is simple and beautiful.

🔧 DIY Tips
Don't. Seriously, this is notifiable electrical work that needs certification. Even if you're handy, it involves your consumer unit and dedicated circuits. Not worth the risk or the invalidated insurance if something goes wrong.
What you CAN do yourself:
- Figure out your hot water usage pattern (write down when you use hot water for a week)
- Check if you're on a standard or economy 7 tariff (affects programming)
- Clear access to your consumer unit and immersion heater switch
- Read your electricity bill to see current immersion costs
This helps me program the timer perfectly first time and you'll see exactly how much you're saving.
Rather leave it to a pro? No problem - that's what I'm here for. Give me a call.
Good to Know
⚡ Economy 7 tariff? Tell me when I book. Changes how we program the timer - you want ALL heating during your cheap night rate (usually midnight-7am), not during expensive daytime rate.
Cylinder insulation matters: If your hot water tank has good insulation, water heated overnight stays hot all day. If your tank feels warm to touch, it's wasting heat - budget for a jacket too.
Older properties: Some Exeter houses have immersion heaters in odd places (airing cupboard, bedroom cupboard, loft). Makes no difference to the timer - I just need to find the circuit.
Frequently Asked Questions
Will a timer actually save me money on my immersion heater?
Absolutely. Most people leave their immersion on constantly 'just in case' which costs a fortune. A timer heats water only when you need it - typically 2 hours before your morning shower and 2 hours before evening dishes. Easily saves £30-50 a month on electricity.
Can you set it up for my specific routine?
Yes - that's the whole point. I program it around when you actually use hot water. Morning showers at 7am? Heats from 5am. Evening bath at 8pm? Heats from 6pm. You get hot water exactly when needed, nothing wasted.
What if my routine changes or I need hot water at odd times?
Every timer has an override 'boost' button. Press it for 1-2 hours of heating outside your programmed schedule. Perfect for unexpected guests or extra laundry days. Timer automatically goes back to normal schedule after.
My immersion heater is really old - will a timer work?
If your immersion heater works, a timer will work with it. The timer just controls the power supply - doesn't matter how old the heater is. Though if it's ancient, might be worth getting it serviced at some point.
Is this something I can do myself?
Legally, no - it's electrical work that needs certifying. Even swapping a timer is notifiable work under building regs. Plus immersion circuits are usually on their own fuse at the consumer unit, not something to mess with unless you know what you're doing.
