System choices

A well designed central heating system will provide fully controllable heating throughout your home.

Whether you are building a new home, carrying out significant renovations or you just want to make your existing home warm and comfortable. It is important to ensure the system you opt for meets both the heat loss requirements of your homes structure & the requirements of your lifestyle.

Here we set out some of the basic considerations to determine the best system for your home

Underfloor Overview

Radiators Overview

Underfloor heating has the obvious attraction of being an invisible heat source but it is important to remember underfloor operates differently to a radiator system. Underfloor heating systems are turned on at the start of the winter period and stay on until heat is no longer required. Underfloor efficiency is dependent on maintaining heat rather than ramping up heat when required. Underfloor systems should be fully controlled as multiple zones.

Radiator systems offer heat performance on a par with Underfloor but because they can deliver heat so rapidly a radiator system does not need to be on other than at the times you require it for example - On in a morning from about 30 minutes before you get up and off when you go to work coming on again for your return home through to the time you go to bed. You can of course have a low level on in the night or on during the day if you wish.

For new build under-floor is a viable option, for existing homes under-floor it is not a viable option radiators are your go to.

In terms of overall running costs an underfloor system though way more efficient by the hour than radiators will have marginally higher operating costs compared to a time controlled radiator system which would operate for far fewer hours over the season. Though you may opt for the hidden heat and warm floor advantages of underfloor, you may also want to consider lifestyle. Do you want full time heating or a more rapid heat up at just the times you require it.

Considerations for underfloor systems

Considerations for radiator systems

Heat source - Best from Air to water HP or from Condensing Natural Gas boiler. Diesel boilers can be used, but we would not recommend, LPG for a floor system.

Hot Water - Is an option from the system though with a Heat pump it is not a full solution.

Control Zoning - The more zones you have the more effective and efficient the system will be.

Control usability - Zone controls should be full control not slave and master.

WIFI control - Is an option to consider.


Heat Source - Condensing Gas or diesel boilers, LPG if you don't mind a larger fuel bill in return for the conveiance, Air to water Heat pumps are only ok if the radiators are suitable (Eg Fan coil type)

Hot water - Can be supplied via a cylinder or on demand from the boilers.

Control room by room - Thermostatic radiator valves should be used in each room.

Overall control - For time and temperature via a master thermostat in a main living area.

Wifi control - Is possible and strongly recommended.

Once you know which system your favoring, the best advice we can offer you is work with a contractor who has heating knowledge and experience who will be able to not only install but service and maintain your system

Make sure you compare apples with apples, make sure what is and is not included, and make sure the installer guarantees his work.
