Combi boiler, or Combination boilers, are the most popular type of boiler in the UK. They’re used by 74% of households.
They’re named ‘Combination’ because they combine a high-efficiency water heater and a central heating boiler all in one package.
Combi boilers are efficient and cost less in heating bills.
That’s because:
System boilers heat your radiators directly and store hot water in a hot water cylinder. They’re usually installed in an airing cupboard or loft. They heat a large volume of water and then store it until you use it.
Standard boilers are also known as Regular, or Conventional . They store hot water in a hot water cylinder, like System boilers, but they’re fed by a separate cold water tank – usually in the loft. There’s another separate tank, called a ‘feed and expansion tank’, usually in the loft too.
The ERP– Energy related products – Label tells you how efficiently a boiler uses energy. It’s designed to help you choose the right appliance and pay less in energy bills. The label rates products from A+++ to G.
A+++ is the most efficient boiler you can get.
It also tells you how loud the appliance is in decibels and how much heat it outputs in kilowatts.
All of the boilers JD Heating & Plumbing Services sells are rated A for efficiency.
A Plume Management Kit directs ‘products of combustion’ away from openings or vents into your property. This keeps you and your family safe.
A magnetic filter , which we’ll provide and install with most boilers. It’s fitted to the boiler, preferably on the boiler return flow. This catches any debris from your system and stops it getting into your new boiler.
A flue is a pipe, like a chimney, that carries waste from the boiler outside. You can see your flue exit on the wall or roof of your home.
Flues can either be square or round in shape.
If the flue is less than two metres off the ground, it’ll be covered by a guard. This looks like a piece of wire mesh covering the end of the flu.
When you buy a boiler from JD Heating & Plumbing Services, we’ll also supply and fit a brand new flue for you, along with all the safety attachments you need.
