Heating controls – getting the selection right

Effective heating controls are a vital part of an efficient central-heating system. With the requirement now for condensing boilers, for ErP compliant heating systems and circulating pumps in the majority of applications and ever more energy efficient radiators or under floor heating systems to share the heat around the home, if you’re looking for even more energy efficiency for your customers, you have limited options. Heating controls manufacturer ESi says it makes huge sense to look more closely at heating controls and consider OpenTherm options which can save up to 15% in energy use.

The decision as to which to include in a new build heating installation or in a heating system replacement project is not always straightforward, with a wealth of options available and a range of combinations of components that can enable the homeowner to be in control of the heating in their home. But it’s vital that the controls installed meet the requirements and on occasions the limitations of the potential users. There is no point installing the latest wifi or blue tooth connected controls if the homeowner or tenant is elderly or vulnerable and unable to fathom out how to use the latest smart controls now available. If they need a straightforward dial control, that is what you should install.

Clever use of controls can help minimise energy consumption by ensuring each room is at the right temperature for comfort, whilst avoiding overheating. This will keep your customer’s home cosy and cut their energy bills which is, at the end of the day, what they want from you.

Whilst most boilers these days feature in-built controls that look after the level and flow of heating and hot water, the range of heating controls that can be used around the home has grown to allow you to be in far more control day to day, than was the case even a few years ago.

The selection of programmers and timers available today are many and varied and range from the simple to the far more complex – or Smart. It is important to choose the controls you install based on the homeowners who will need to use them. So it is vital that all domestic controls are as easy to use as possible – ESi has achieved this following considerable research and customer trials.

Most controls manufacturers offer a range of programmers from a simple 1 Channel version to a 3 channel Multi-Purpose Programmer which enables the installer to comply with Part L of the Building Regulations by providing separate timed heating control for living and sleeping zones in a home, whilst also providing timed control of hot water. Many will offer 24 Hour / 5/2 day and 7-day programming options for each channel. And for social housing or private landlords there are programmers that also feature a “Landlord” option to encourage social housing and private tenants to allow access for annual maintenance, often a real challenge for landlords.

Unless you have a smart system which allows you to control individual radiators in your home, there’s usually only one room thermostat per heating system. It controls the temperature of the whole house based on the temperature of the room it’s in. You can purchase a range of programmable room thermostats – both hard wired and wireless models. A room thermostat is best located in the living room or the warmest room in the house.

A programmable room thermostat lets the homeowner choose what times they want the heating to be on and what temperature it should reach while it’s on. A seven-day timer makes it possible to set a different heating pattern for each day while 5/2 programming offers different options for weekdays and weekends.

For people who prefer a control dial to push button controls to control changes to heat in a room, these are still available from some manufacturers and offer the simple answer they are looking for. Available with or without an LCD display the homeowner simply has to turn the dial to the desired temperature. Again either hard wired or wireless options are available. And for people who simply want a standard mechanical room thermostat these are still available as well. It’s horses for courses and there are options for every potential user.
