Frequently Asked Questions
How do I know if my heating system needs maintenance?
How often should I service my heating system?
We recommend an annual service — ideally before the colder months. This ensures your radiators, cylinders, and thermostats are working efficiently and safely.
Can you replace old radiators with modern ones?
Yes. We supply and install a wide range of energy-efficient radiators that heat faster, retain warmth longer, and look great in any interior. We’ll also ensure your system is balanced for even heat distribution.
My radiators are warm at the top but cold at the bottom — what does that mean?
This usually indicates a buildup of sludge or trapped air in your system. Our engineers can bleed your radiators or carry out a power flush to restore full performance and prevent future issues.
What is power flushing, and do I need it?
Power flushing is a cleaning process that removes rust, sludge, and debris from your radiators and pipes. If your heating system is noisy, slow to heat, or uneven, a power flush can significantly improve efficiency and heat output.
How long does it take to replace a hot water cylinder?
Most cylinder replacements take around half a day. We’ll remove the old unit, install the new one, and test your system before leaving — ensuring everything works perfectly.
Can you upgrade my heating controls to smart thermostats?
Yes. Smart thermostats allow you to control your heating remotely from your phone, create custom schedules, and monitor energy usage. They’re a great investment for efficiency and convenience.
What’s the benefit of balancing radiators?
Balancing ensures that each radiator receives the correct flow of hot water, improving comfort and efficiency. It prevents some rooms from being too warm while others stay cold.
Do you work with both vented and unvented cylinders?
Yes — our engineers are trained to work with both systems. We’ll help you choose the right option based on your property type, water pressure, and heating setup.
How can I make my heating system more efficient?
Regular maintenance, bleeding radiators, insulating your cylinder, and upgrading to thermostatic radiator valves or smart controls can make a big difference. We can assess your system and recommend tailored improvements.
