How much do new radiators cost?

But how much will it cost to get new radiators in your home? New radiators can cost as little or as much as you want to depending on the types of radiators and how many you need. This article should help you with everything you need to know before purchasing your new radiators. 

What types of radiators are there?

The most common types of radiators are central heating radiators. These can cost anything from £15 up to £1,000. Radiators are basically hollow metal containers that allow hot water from your boiler to be passed through which heats up the air around it. How quickly the air around the radiator heats up will depend on the type of radiator, what they are made of, and how big the radiators are.

Single panel radiators £15 to £500

Single panel radiators are slim in design and are widely used in homes across the UK. They are often ridged to increase surface area to help heat more of the air around them when the hot water is circulated around them by a boiler.

Double panel radiators – £30 to £1,000

Basically the same as a single panel radiator but are bulkier and cover more surface area and contain more hot water for faster heating of a room or area.

Cost Of Installing Radiators

Boilers are placed under three categories. The boiler suitable for your home would depend on various factors such as the size of your household, the size of your property and budget.

What Boiler Size Do I Need For My Radiators?

Finding the right boiler for your property depends on several factors such as the size of your property, the number of rooms, and bathrooms. When replacing your boiler, it is essential to avoid picking the same size as your current model. The size of a boiler is not measured in accordance with its length or width, but by the power, it generates in kilowatts(kW). Therefore, the bigger the kilowatts, the bigger the size. 

Boiler for 8 to 12 radiators

For a system boiler in the range of 12 and 15Kw, 8 to 12 radiators will be ideal for heating your home compared to a medium-sized property, which requires an 18kw boiler to run between 12 and 20 radiators. More so, the number of radiators a 24kw boiler heats will depend on its type. For example, a Combi Boiler in the range of 24 and 27kw can control up to 10 radiators, while a 24kw warmth in the system model or heat only can take up to 15 radiators. 

Boiler for 13 to 20 radiators

For a System or Conventional boiler, any size between 27 and 40kw is enough to keep between 20 radiators pleasant and hot. Then again, 30kw heat-only and system heaters can warm 13 to 20 radiators. For a large household, a boiler model of 35kw is proficient in heating up to 20 radiators.

New Gas Boiler And New Radiator Cost

84% of the UK’s 27 million homes are connected to the gas grid, which implies they can have a gas boiler automatically fueled. How many radiators you have in your home will affect the size of the boiler in your home and the amount of gas used. Properties in the rural areas which have not been linked to the gas network will need to utilise alternative fuel like electricity, gas, or biomass for their boilers. Despite this, most homeowners are settling for boilers that use renewable energy like biomass to check their carbon emissions. 

How Much Does It Cost To Install New Radiators UK?

Suppose you are looking to change the central heating system comprising the boiler, thermostat, and rerouting the radiator water lines and gas supply pipe. In that case, you should expect to pay over £2,000. If you have a leak in your radiator then this could also be a reason pressure is dropping from your boiler and making your central heating system much less efficient.

Cost Of The Various Types Of Radiators And Valve 

Manual Radiator Valves

A manual radiator valve is easy to use. The valve can easily be turned “On” or “Off” and keeps the radiator at a consistent temperature. Despite being easy to use, manual radiator valves are less energy efficient because of the steady temperature and water stream. Generally, manual valves are more appropriate for use in rooms fitted with a reliable thermostat. There are various types, including the chrome angled radiator, Torino chrome, white bologna radiator, and Arroll UK manual radiator valve costing between £12 and £47.

Thermostatic Radiator Valves

A thermostatic radiator valve (TRV) has an inbuilt wax or liquid-filled sensor in its head, which can adjust to the radiator’s temperature by either increasing or decreasing the flow of water through the radiator. This makes TRVs more energy efficient compared to the manual radiator valve. However, it is not ideal for use in rooms with a thermostat to avoid causing conflicts in room temperature readings. Among the popular brands of TRV is White chrome angled TRV, Drayton TRV, and Cassellie RVA, pricing from £8 to £33.

Lockshield valve 

A Lockshield valve is ideal in controlling the flow of water emerging from the radiator. The Lockshield is additionally intended to help balance a radiator to ensure efficient heating and at a similar rate as the water being dispersed equally in the system. Lockshield is relatively less expensive than the manual radiator valve and TRV with a price ranging between £5 and £20 depending on its features.  

The prices differ significantly depending on the type of boiler system you choose and the quotes you are offered to have your new boiler system installed. These prices vary due to several things; however, you should seek additional advice to determine what is most suitable for your property. Visit to learn more information about the boiler systems.
