Frequently Asked Questions

Is it an efficient boiler?

Provided with an external heat exchanger and a Riello Low NOx technology, these boilers are A rated for both efficiency and emissions. The heat exchanger, which is unique to Warmflow, enables more efficient heating meaning that they use less fuel to provide you with hot water at the tap - saving you money on your water bills.

Do I need a system boiler?

The Agentis External system boiler is designed to be installed outdoors, adjacent to your oil storage tank and hot water cylinder. It can provide high mains pressure hot water directly into your central heating system, but you will need a backup ‘tank in tank’ hot water cylinder for fixtures such as baths and showers.

What about the warranty period?

Warmflow offer a standard parts and labout warranty period of 2 years on the Agentis model.

Will it be powerful enough for my needs?

There are a range of models available in the same range, from 21kw up to 33kw so there will be a boiler suitable to meet your home's heating and water requirements.
