Best Conservatory Heaters & Radiators
Keeping your conservatory the right temperature year round can be quite the challenge, if your conservatory is anything like mine, it’s far too hot in the summer and freezing in the winter.
Thankfully, thanks to advances in electric radiator technology you too can make the most of your space when the cold weather starts to hit!
Our handy guide below will give you an idea of what type of heater to buy for your conservatory.
We recommend you start by reading our top 10 conservatory heaters list directly below.
Then beneath that you’ll find our comprehensive guide that will help you choose the perfect heater for your needs.
If money is not an object, then we always recommend underfloor heating in a conservatory as it is by far the most effective way of keeping the heat in.
Otherwise infrared, panel or oil based / convection based heaters are the affordable and less intrusive option available to you and what we will be covering in our guide today!
When you’re looking for a heater for the conservatory, there’s no blanket right answer as every family or individual has different needs.
However for simplicity’s sake, we recommend infrared heating panels above all other heaters for the conservatory as they tend to come with the most features and offer a fantastic balance of affordability and practicality – things like timers, remote controls, Wi-Fi control (Alexa / Google Home) and IFR motion detecting units are commonly seen on even the cheaper types of these heaters.
We think it’s quite simple – when choosing your new conservatory heater, we recommend infrared heaters if you have children or pets as these are much safer and more energy efficient than convection based heaters.
Wall mounted infrared heaters are fairly cheap to run as you’re not wasting energy trying to heat up the air around you – this is particularly important if you’ve got an older conservatory or one with a polycarbonate roof.
There are a number of infrared heaters available, from no-glare panels and ceramic heaters to a more traditional low-glare carbon fibre heater or the fire-red halogen and quartz heaters.
We also prefer infrared panels over convectional heaters as when Spring or Autumn rolls around, you can keep the doors and windows open and still use your heaters without wasting money or energy.
Prices start from around £60 for budget units and can go up to £600+ for designer invisible glass window heaters.
From a safety stand-point, most infrared heaters aren’t cold to touch and will run at a temperature of between 90-100c but because they use far-infrared technology it won’t cause burns or scalding when brushing past them. They are also less of a fire hazard than traditional fan style electric heaters.
It’s hard to pick when there are so many good infrared panel heaters on the market but after hours of research we highly recommend the ElectriQ 700W Low Energy Infrared Panel or the Veito range of heaters for your conservatory.
The electriQ 700W Low Energy Panel Heater will set you back around £100 – it comes with all the advanced features of a top-range heater at a fraction of the price.
It is Wi-Fi enabled and has an adjustable thermostat.
Easy to install and depending on your current electric tariff and whether you’ve got it on full power or not, you can expect it to cost between 5-8p per hour to run.
Where can I the ElectriQ 700W?
These low-glare heaters are traditionally found in patio heaters and far-infrared heaters.
They’re fantastic for sheltered areas and provide a low-intensity heat over a large area.
They come in free-standing, wall mountable or ceiling hung variants.
While they’re about as expensive as convection units they will cost less to run due to the efficiency of infrared heating over convector heaters so you’ll save money in electric over the long run!
Not everyone likes the glow of these heaters but we like the ambient lighting that they provide.
The Veito range of heaters aren’t cheap but in terms of heat distribution and practicality these carbon fibre based heaters are suitable for indoor and outdoor usage.
|Heater||Approximate Cost||Heating Area|
|Veito Blade 2000||£250.00||25sqm|
|Veito Blade S2500||£299.99||30sqm+|

Most small to medium sized (3x3m to 4x4m) will only need 1 or 2 radiators to keep warm. But it’s always better to calculate how many BTU’s are needed before purchasing your heater.
We recommend using this BTU calculator by Haverland to give you an idea of how many heaters or what wattage you need to heat your conservatory.
Do I Need
Planning Permission or
Building Control Certification
to Install Conservatory Heaters?
The simple answer is no, as long as you’re installing an electric radiator system like the one’s we have recommended in our guide, then you will not need planning permission to do so.
However if you’re connecting a traditional radiator to the same central heating loop that the main house uses, you will be subject to building regulations as this qualifies the conservatory as a home extension instead of a conservatory.
To ensure that you’re exempt from building regulations, the radiators or heaters in your conservatories need to be independent from the main heating system in your home and have their own on / off switch.
If in doubt, contact your local council for further information.
LOT 20 is an Ecodesign legislation from the EU which focuses on electrical space heaters. The EU 2015/1188 legislation requires all heaters manufactured in the EU from January 2018 comply with a minimum efficiency standard under “LOT 20” of the EED or the Energy Efficiency Directive.
This applies to all electric heaters using gaseous or liquid fuels and also includes panel heating, underfloor heating, gas fires and space heaters.
What does this mean for you? Well, as a consumer if you’re installing an electrical heater yourself, you don’t need to purchase a LOT 20 compliant heater, but if you need an electrician to install the unit then they are required to install LOT 20 compliant heaters only.
What’s good about LOT 20? Well, to help achieve a 20% energy saving by 2020 heaters are now being manufactured with additional insulation and energy saving features to lower costs and increase heat efficiency.
While this could mean slightly higher purchase prices, on-going savings on electricity and higher heat retention quickly negates this slight increase in cost and lower Co2 emissions are essential to try to prevent the rapidly increasing effects of global warming.
The current average cost of electricity in the UK is approximately 14.37p per kWh (as per UKPower – February 2020) – most residential tariffs are lower than this by a few pennies – as an example, on my current tariff I’m paying 11.4p per kWh with a standing charge of 26pence per day.
Price per kWh also changes by locality, North Scotland and the South West pay on average 1.5-2p per kWh more than the East Midlands or Yorkshire.
To calculate how much our heaters cost to run we take the wattage of the heater and multiply it by the cost per kWh.
For example, a 1500W or 1.5kW heater would cost me 11.4p x 1.5 = 17.1p per hour to run.
Modern heaters have thermostats and advanced cut-outs so once the conservatory has hit your desired temperature it won’t be running at full pelt anymore so it’s hard to calculate exactly how much it’ll cost to run but it’s better to budget for full power.
If we ran our 1.5kW heater for 3 hours each night during the winter months we’d calculate it as follows:
17.1p per hour x 3 hours = 51.3p per evening
x 30 for the month = £15.39 per month
x 3 for the season = £46.17 per winter
However if you’re using a singular infrared panel running at 700W our monthly bill would be just £21.55 assuming the heater is running at full power for 3 hours per day.
We get asked this one a lot. Infrared patio heaters would in most cases be suitable for use inside a conservatory. Wall mounted patio heaters usually require a certain amount of clearance (20-30cm depending on brand) both above and below to prevent a fire risk.
Infrared panel heaters are cheaper and more efficient to run inside than patio heaters – they’re also cheaper to purchase and will provide far-infrared heat rather than near-infrared which is reserved for outdoor and unsheltered areas.
The short answer is: Yes you can use an electric (not GAS!) patio heater indoors but there are more efficient options available to you. Why not read our guide to our best patio heaters available this year and learn more!
