Simple Low Cost Upgrades & Solutions
All new boiler installations must have one of these fitted. If your installer has not fitted you one or you chose to opt out, then think again.
Modern boilers are super efficient because they use thin superconducting metals.The problem is that the passageways within these boilers can easily become blocked with debris (magnetite) from your old central heating pipework and radiators.
Most people forget that the pipework in your house was installed over 40 years ago, 40 years worth of corrosion, rust circulating around your system.
You spend £££ on a nice shiny new boiler and then contaminate it with 40-year-old filthy central heating water!
Honest Advice time: If your boiler is old, do not waste your money.
If however, you are experiencing any of the following:
Radiators are cold at the bottom and hot at the top
Modern Boiler Sounds like a kettle
Boiler takes forever to heat up the house
Boiler not staying on long enough
Then you are most probably need to address the dirt in your system.
Low-cost/short-term solution: Add a filter
Medium-cost 5-8 Year Solution: Add a filter and have your system Powerflushed, have new central heating pipework installed
High-Cost long Term solution 10+ years: Install New Boiler and New central heating Pipework, no need for a flush
Ignore this advice at your peril! Use a Professional Powerflush company.
There are a lot of cowboys out there charging £200-300 for a "Flush". There's a reason they are cheap. You may as well take that money and flush it down the drain.
There are company's out there that take pride in what they do and this really is a specialist field, if you want it done correctly. Click here for a company Trinity Heating Solutions would recommend.
Cheap and a must if you have a combi boiler. If you live in a hard water area (check here) then it really will prolong the life of your boiler.
Now you may not be aware that you have one of these either in your boiler or on your system. All combination (combi) boilers have one of these. Most new builds will have what is known as an unvented system.
What are they and why are they so important? They are on your system to take the expansion of water when it heats up. Older systems had 'Header Tanks' in your loft, which took the expansion of water when it heated up.
If you have to 'Top' your boiler up (system pressure low) then somewhere on your system will be an expansion vessel.
Within the gas industry, a lot of engineers overlook this and fail to check 2 things:
1 - Has it got the correct pressure?
2 - Is the expansion vessel correctly sized for the heating system?
Keeping it simple for the consumer when any of the questions above are answered no, then you are going to have lots of niggling problems, culminating in one big one.
If your vessel is not checked on a service and it is 'Flat', then when your water expands it has nowhere to go, and it has to go somewhere! So it finds weak spots on your system.
You get leaks, loss of pressure problems and poor boiler performance. The components within your boilers water circuit will have to cope with a lot of stress and pressure on them and will eventually fail.
The cost to you is lots of labour call outs + parts!
Undersized systems will suffer with the same. Why would your system be undersized?
When your boiler was installed your installer, if he was a professional, they would have calculated the volume of water within your system and would have sized your vessel correctly.
If your boiler is a combi boiler then you will have a 6-8 ltr vessel inside. That will just about cope with a 3-bed house, with 6-9 normal sized radiators.
If you have added an extension, added a bathroom, or increased the number of radiators in your home, then your boiler will not be able to cope with the increase in water.
A really good piece of advice, if you currently have a combi boiler and are currently not suffering any issues, add an external vessel to safeguard yourself for further ahead.
