Looking to spec & install some destrat fans to improve the heating efficiency in a largeish warehouse I look after.

Have spec'd them up for size etc & I am looking at the following manufacturers:

Ambirad
Powrmatic
Roberts Gordon

Anyone got any other manufacturer recomendations or experience of the above?

Powrmatic would be my choice - used them in some big MoD sheds recently and working well.

Ambirad are also good.

as an alternative, take a look at Destratair units - they are mounted at low level and provide a large capacity recirculation that keeps the temperature gradient to within 1 or 2 degrees - part of (or used to be) Nuaire Group

in addition, Puravent EliTurbo units are good quality and reliable.

What's the heating system currently ?

High level gas fired warm air heaters (mix of Powrmatic & RG Combats) in the main warehouse areas which means the majority of the heat ends up in the roof & lower level is a lot colder so they are constanly on!

OK - pretty normal stuff then, with the usual problem.

Depending on the height and the noise you can tolerate, I'd do a quick comparison between powrmatic and destratair as alternative aproaches (you could ask them for estimates/quotes - they both have good technical departments) and go from there in terms of advantages/disadvantages and present to your client - involve him in the process

Have looked at the Destratair website & quite like their lower level solution. Have sent them an equiry so will see what they come back with.

The client is the company I work for so I'm convinced it's worthwhile but I have to persuade the bean counters that it's cost effective!

OK - as I said, do the advantages and disadvantages, including H&S and maintenance - see if you can calculate savings and thus payback

Good luck - don't use the phrase "The trouble with you, is you know the cost of everytning and the value of nothing" - not a good opening line I find
