Most people searching for “solar PV + heating systems” discover very quickly:
you can’t buy a full roof-mounted solar heating system on Amazon.
But what you can buy — and what thousands of UK homeowners already use to reduce energy bills — are modular solar + heating combos that work beautifully alongside your existing setup.
These are not fantasy “heat your whole house for free” packages.
They are real, practical add-ons that make your heating cheaper, smarter, or more independent.
This guide walks you through the best combos you can actually order on Amazon UK today, how they work, who they’re best for, and the realistic savings you can expect.
⭐ What Counts as a “Solar PV + Heating Combo”?
In everyday UK homes, it usually means one of these:
- Solar power station + low-watt heater
- Solar immersion controller + hot water tank
- Smart thermostats + solar-timed heating control
- Portable solar panels + supplemental daytime heating
- Battery storage + heater for off-peak or backup heat
Each combo offers different benefits — some save money, some add convenience, and some provide emergency warmth during blackouts.
Let’s break them down honestly.
1. Solar Power Station + Low-Watt Heater (Most Flexible Combo)
Best for:
- Garden offices
- Sheds & garages
- Home workspaces
- Flats where installation isn’t allowed
- Emergency heating during power cuts
How it works
A solar power station stores power from either portable solar panels or off-peak electricity. You then use that stored energy to run a small heater, heated throw, dehumidifier or other low-watt devices.
This setup is ideal for heating one room without touching your main home system.
Honest benefits
✔ Total plug-and-play
✔ No electrician required
✔ Works in rented homes
✔ Great for evening “top-up heat”
✔ Doubles as blackout protection
Honest limitations
✘ Won’t run a 2kW heater for long
✘ Best for rooms, not full homes
🔌 Amazon-Friendly Combo Example
1. Jackery Explorer 500 Power Station
A reliable mid-size solar generator perfect for home offices, sheds and emergency heat sources. Can power low-watt heaters, throws, routers, lights and more.
2. Byecold 600W Panel Heater
Low-watt, silent and ideal for running from a power station. Great for taking the edge off a cold room.
Together, these create a realistic, usable solar-powered heating setup for small spaces.
2. Solar Immersion Controller + Hot Water Tank (The Money Saver)
If you already have a solar PV installation at home, this is arguably the best upgrade you can buy on Amazon for heating-related savings.
How it works
A solar diverter sends surplus solar energy into your immersion heater instead of exporting it to the grid for pennies. This gives you:
- Hot water heated by the sun
- Less reliance on your boiler
- Lower gas or electricity bills
Honest benefits
✔ Fully automatic
✔ Can cover 50–90% of hot water use
✔ Works extremely well on sunny days
Honest limitations
✘ Requires an existing solar PV system
✘ Requires a cylinder (not a combi boiler)
✘ May need an electrician to install
🔥 Amazon-Friendly Combo Example
3. iBoost+ Buddy Solar Diverter Monitor (for solar immersion systems)
A popular add-on for homeowners using immersion diverters. Helps you time hot water heating to maximise free solar.
4. Eastronic Energy Monitor Plug (track heater & immersion usage)
Lets you monitor real-time consumption so you know exactly when you’re running on solar vs paid electricity.
3. Smart Thermostat + Solar Timing (Free Heat When the Sun Is Out)
You don’t need a fancy heat pump to benefit from solar.
A smart thermostat can massively improve how your heating syncs with your solar production.
How it works
- Your thermostat is programmed to heat rooms when solar is producing best
- Heaters or electric radiators run from your “free power window”
- Your boiler fires less often because you’re pre-heating smartly
- Works beautifully alongside immersion systems
Honest benefits
✔ Makes existing solar far more effective
✔ Reduces wasted boiler cycles
✔ Helps avoid peak-rate heating
✔ Perfect for zoned heating
Honest limitations
✘ Doesn’t generate power on its own
✘ Savings come from smart scheduling, not hardware
📱 Amazon-Friendly Combo Example
5. Tado Wired Smart Thermostat Starter Kit V3+
A highly rated thermostat with excellent scheduling tools. Works well for timing heating with solar production peaks.
4. Portable Solar Panels + Daytime Solar Heating
This is the easiest way for renters, flat-owners or beginners to benefit from solar without installing anything on the roof.
How it works
You set up foldable solar panels in the garden, on a balcony, patio or shed roof. They feed into a power station or controller, which then runs:
- Small heaters
- Dehumidifiers
- Heated throws
- Ventilation fans
Honest benefits
✔ No installation needed
✔ Works anywhere sunlight reaches
✔ Great for daytime warmth in sheds & offices
Honest limitations
✘ Won’t heat an entire house
✘ Sunlight is essential
✘ Best used as a supplement, not a main heat source
☀️ ALLPOWERS Portable Power Station (Solar Charging Ready)
This model works as both a compact solar generator and battery storage unit, making it ideal for:
- Using portable solar panels for off-grid heating support
- Running low-watt heaters
- Powering heated throws
- Charging devices during blackouts
What These Combos Can — and Can’t — Do (Honest Truth)
✅ What they can do:
- Reduce heating bills
- Give backup heat in power cuts
- Improve solar self-consumption
- Provide cheap heat for small rooms
- Cut hot water costs significantly
❌ What they can’t do:
- Heat an entire home
- Replace your boiler
- Solve winter heating on solar alone
These setups are support systems, not full heating solutions — but they do make a real, noticeable difference in comfort and energy spend.

👤 Author Insight
“I don’t actually have solar panels on my own home (yet), but I kept seeing people online talk about how they pair solar with heaters, batteries and smart controls. That’s what pushed me to dig into the real setups ordinary households use — not the expensive full systems, but the smaller, practical combos you can actually buy on Amazon. After researching these options properly, I was surprised at how much you can do without an installer, especially for heating small spaces and cutting hot water costs. It’s made me seriously consider starting with a portable setup before going all-in on roof solar.”
