Heating your home

Diamond Heating & Cooling highly recommends Worcester Bosch boilers which have been voted a Which? Best Buy for the 8th consecutive year running. Worcester Bosch boilers come with up to 12-year guarantee on parts and labour providing you with peace of mind. Our engineers’ knowledge and expertise extend to all boiler manufacturers including Ideal, Valliant and Glow Worm, to name a few.

When it comes to selecting the right boiler for you, it’s not as simple as just choosing a brand. We understand that budget can have a huge impact on your decision process and we are here to help you make that decision based upon what you can afford, without compromising quality.

Central Heating

Maintaining your system

Diamond Heating & Cooling believes that prevention is better than cure. That is why, when we service your boiler, we will offer you a water test for your central heating system. This will establish early the quality of your system’s water and detect problems like sludge, deposit, rust and scale deposits. If some of those are present it can cause major faults with your boiler as it gets clogged up with debris from your system

Our engineers’ knowledge and expertise will also ensure your whole system is working efficiently, checking pipework, pumps, radiators, thermostatic valves and central heating controls, so that your appliances reach our highly regarded Diamond standard.

Power Flush & Filters

System cleansing

A power flush will benefit not only your central heating system but your pocket too. Removing sludge and scale will improve the flow of water around your system, saving you money on fuel bills.

We recommend installing a system filter which works by collecting corrosive material, such as iron, before it circulates around your system, keeping it in one place.

Your filter will need to be serviced every 12 months and this can coincide with your regular boiler service. The benefits of a system filter will ultimately prolong the life of your boiler and prevent iron oxide materials from clogging up the system, ensuring your home is more economically efficient.

Smart Controls

Smart Thermostats

Replace your old thermostat with a new smart version to experience a new level of comfort and control, whilst saving energy and money. With a smart thermostat you can control your heating and hot water from anywhere in the world.

When you’re coming back from holiday and don’t want to walk into a cold house, or you’ve stayed at work longer than expected, a smart thermostat means you can turn the heating on or off whenever you want to.

With many different brands on the market Diamond Heating & Cooling have carried rigorous testing, to find the best options for our customers. For most users, we recommend Tado, it has all the key features of other brands whilst being simple to use. We will however depending on our customers’ needs recommend and fit other brands such as Hive, Nest & Worcester Bosch.
