Maximising energy efficiency

Maximising energy efficiency

Homeowners across the UK took a collective gulp on 1st January when the OFGEM energy price cap was raised again. There may be good news on the horizon – with energy bills set to come down a little, later on in the year – but fundamentally, the higher energy bills we’ve seen over the past few years are likely to stay. Gareth Ash, Marketing Communications Manager at Danfoss looks at how installers can help their customers to save energy and cut their bills, during the worst cost of living crisis we’ve seen for generations.

Changing focus

Until recently, comfort was the primary driver for UK householders when it came to choosing a central heating system. However, increased awareness of the climate crisis – alongside spiralling energy costs – has put energy efficiency sharply into focus. The interesting thing for installers to stress is that no matter what the heating source, unless it’s controlled well, consumers are not going to be able to optimise their energy efficiency. Suggesting a few simple additions or tweaks to an existing system that will create visible savings, fast, ensures that when the customer needs a replacement system, their helpful installer will be front of mind.

Quick fixes for big savings – Electronic Room Controls

Controlling their heating system’s operation time and desired temperature by using an electronic room control is one of the easiest way for householders to balance comfort and energy use. Adding heating zones into the mix, which is possible with modern controls like Danfoss’s TP5001, will enable homeowners to further control their energy use, without compromising on comfort levels.

Thermostatic Radiator Valves (TRVs)

Good old TRVs are one of the best ways that homeowners can optimise their heating bills. Not over-heating rooms that are rarely used is a no-brainer for customers wanting to slash their bills without having to watch TV with their coats on!

System Balancing

As every heating professional knows, hydronic balancing is the process of optimising the flow of water in a hydronic heating (or cooling) system by balancing the system pressure. Pressure drop in a central heating system occurs because of the way water behaves when flowing through any pipework system. Balancing ensures that water flows equally to individual radiators and so prevents cold or hot spots occurring, or the property not heating at all. As well as the discomfort factor, the efficiency of an unbalanced system is significantly reduced, increasing energy consumption and fuel bills for consumers. Furthermore, TRVs with too much flow may not operate properly and can become noisy as water streams through the valves, particularly as they start to close when the room temperature increases. These days, balancing radiators has bever been easier, thanks to Danfoss’s RAS-B2 valve, which features a differential pressure controller that ensures all radiators throughout the home get the heat they need throughout the year.

Mixed system compatibility

There are a number of reasons why many homes now have mixed Central Heating systems. The move away from fossil fuel burning systems is one of the them, as is something as simple as getting an extension! Having controllable heat and hot water is essential in order to maximise energy efficiency and optimise comfort for residents, no matter how a system is put together. Choosing a reputable supplier for heating controls is the first step in ensuring that the fine line between comfort and efficiency is reached.
