Your guide to installing your product

All our self-install products come with a manual and diagram. Some of our larger products come with a kit which includes a step-by-step guide.

Should I use vented or unvented

Both of them has its own advantages; unvented offers more pressure yet vented can continue to work even when the mains water has been turned off.

Choosing a cylinder size that is fit for purpose

Your choice depends on a number of factors. These include the size of the space available to you, the strength of the mains pressure and details of your existing heating system. We would recommend you measure your space and speak to one of our friendly operatives on 01473 276686.

Frequently asked questions

Electric boilers are compact in size and do not take up much space. There is no need for flues, storage tanks or separate hot water storage, making them ideal for small flats and smaller spaces.

Elnur electric boilers do not come with a flex as they are subject to different installation methods other than for example a radiator or panel, whereby the connection must be hard wired by a competent engineer.

The Elnur RFE electric radiators all have child locks on the settings panel to stop little hands from tinkering with your heating. The Elnur Connected range however, do not have a lock available on products in the range.

Stiebel Eltron SN 5 SL GB Small Water Heater 5 Litre

Good little water heater at good price

View product

Nice little water heater, but customer service poor. Did not get order acknowledgement when order placed, so re ordered and sent message to company which was not responded to appropriately. They sent out two heaters and I had to to refuse one and request bank refund on second payment as I had not authorised the purchase of two and the company would not respond to my queries. Their website refreshes back to the checkout status, appearing that the order was unsuccessful. Then I receive an email ,explaining they had received the returned heater and wanted to know if this was in error, meaning they clearly have not read or taken on board my emails.

I am so sorry our website seemed to have issues on that day. I have looked into this for you and can see that my colleague has discussed and resolved the problem with you.
Please do not hesitate to contact us in the future with any issues and we will be happy to resolve these ASAP for you.
Thank you for taking the time to complete a review. It helps us focus on improving our customer service.

Good price. I have another Gledhill cylinder which works well so I expect this one will be the same.

The price for this cylinder was very competitive. The delivery was amazing - I ordered it at lunchtime and it was delivered to my door in Cornwall the following morning. That’s great service.
