Customer Brief:

In March 2024, we were asked to install one Winterwarm XR100+ and three TR150 gas-fired, warm air, space unit heaters into these 40,000 sq. ft. warehouse premises.

Features of the Heating System:

These premises are a retail warehouse, so on this project we were asked to provide background heating for the aisles where customers are moving around (using the TR150s) and to spot heat the checkout area (using the XR100+).  We were replacing older, less efficient Combat Elite Pro gas unit heaters and we decided to reduce the height that the heaters were suspended at, to more easily transfer the heat to the lowest levels of the building.  We suspended the heaters from the purlins and we flued the emitted gases through the roof.  Due to the height of the roof, we organised to work with our approved local roofing contractor to seal the roof flues.  These heaters can modulate the heat output and will automatically switch to low fire when the thermostat detects that the area has reached the desired temperature, this can save up to an additional 30% (compared to non-modulating heaters).  As an example of this the TR150 heaters can start up at 140kw to heat the building from cold, then will modulate down to 100kw when the space is to temperature, similarly the XR100, varies from 87kw down to 57.  The installation was completed in five days and we worked in close consultation with our customer to close sections of the warehouse on a rolling programme, so that it could stay open and valuable custom was not lost.

The heater installed by Warmco is absolutely brilliant! It has surpassed our expectations… it is very efficient on gas consumption and overall working with Warmco will save us a lot of money in future. All in all we are over the moon with our heating system and would be very happy to recommend Warmco’s services to anyone.

Russ Moore – A S Plant, Mansfield October 2020

Warmco were very quick to respond to our request for a survey and to quote for our heating; much faster than the response time that I have generally come to expect form other companies. The engineers communicated well and worked round our site requirements, to create minimal disruption to ourselves and our customers. We are pleased with our heating, it is working well. Warmco have been available to assist with giving advice on our system. Overall, we were very impressed from the start to finish of our dealings with Warmco.

Mark Donoghue – Brownhills Leisure World – November 2020

Overall I'm happy with the service provided by Warmco. The site visit and quoting process was good. The install guys were good, on time, seemed to get on with the job and completed it on time with good communications. As for the heaters, as it hasn’t been too cold as yet, I can't comment fully on how effective they are.”

Darrell Freeman – Big Dude Clothing, Ellesmere Port October 2020

Warmco were knowledgeable when it came to recommending a heating system to us. They explained the system in a way that gave us confidence in the products and services they were offering. Most importantly, the price was right. The installation was great, the engineers came when we were told they would, worked round our warehouse operations, did a neat job of the installation and were clean and tidy. We are pleased to say that the heating does exactly what we need it to do.
