How can I work out which size radiators I need?

Our BTU Calculator tool will help you identify suitable radiators for the specific room(s) in question.

As a guide, in our experience we’ve found the typical room size of the average 3 bedroomed house requires the following radiator sizes:

Lounge = 1400 x 600 double
Dining room = 1200 x 600 double
Kitchen = 900 x 600 double
Bedroom 1 = 1400 x 600 single
Bedroom 2 = 1200 x 600 single
Bedroom 3 = 900 x 600 single
Bathroom = 600 x 600 double

How long does delivery take?

We aim to deliver within a week, often much less depending on your location.

Deliveries in Scotland can take longer as we cover the whole country from our Glasgow depot.

You can take a look at your area on our Delivery estimator, but please note, this will give you an idea of how frequently we deliver to those areas, but will not be you guaranteed delivery date.

As soon as we process your order, one of our team will either call you to book in your delivery if its a large order that will need confirmation, or you will receive an email with a delivery date in it. (Please ensure you check your spam folders in email)

If the date we notify you of isnt suitable, please call the number in the email to reschedule directly with your delivery depot.

What if I need an urgent delivery?

Sometimes you just have to know how quick, we understand.

We recommend you phone the nearest depot to you and ask them what day they’ll be in your area next.

If the delivery day they give you is what you are hoping for, grab it with them on the phone, place your order as soon as possible. We take a lot of orders every day and the slot the store gives you may be filled by the next call they take.

We understand you need to know when.

Once your order is placed, we’ll confirm an exact delivery date with you as soon as we process your order.

Do you use couriers?

We don't like to use couriers if we can help it.

The items we sell, and the way we sell a lot of it in package deals means our deliveries are bulky and prone to damage when couriers get hold of them.

We will only deliver boilers, radiators and fragile items on our own transport, we reduce any delay or damage to a minimum this way. Couriers do not kno wheating products like we do, it is just another box to move from A to B.

If your order is small, below 2kg we will more than likely deliver via DPD Local on a next day service.

Follow links through to various manufacturers sites, as each manufacturer will have its own terms and conditions for qualifying for longer warranties.

You do not want to miss out by getting the wrong installer for some boilers etc.

Do I need a magnetic filter on my boiler?

A magnetic filter is an option.

It will extend the life of your heating system when used in conjunction with a system inhibitor to stop the formation of rust.

What is the difference between a Vented and an Unvented Cylinder?

The main difference between a vented and unvented water storage cylinder is that an unvented hot water cylinder takes its water supply directly from the mains.

Whereas a vented cylinder is connected to a water tank by a vent pipe

You can get hot water out of an unvented cyinder at a much better pressure than a traditional vented cylinder as it is pressurised.
