Customer Brief:
In March 2021 this customer approached us to replace five of the existing NVX140 Powrmatic gas suspended unit heaters, within this 100,000 sq. ft. space which were faulty. We suspended two of our Warmco / Winterwarm HR120 condensing heaters within the factory area and the other three heaters were suspended at a height of 8m-9m, above the stored insulation products.

Features of the Heating System:
We specified a heating system with room sealed flues, which burn clean air from outside the building. This avoids contaminants being burned which, in an environment with contaminated air, allows the lifespan of the heaters to be extended. Additionally the Winterwarm HR120 heater comes with a robust stainless steel heat exchanger, which also extends the life of the heater and allows us to offer a ten year warranty. The heater comes with a modulation feature as standard, which allows it to initially heat up the space at full 115kw capacity, then once the space is up to temperature, the heater switches to 37kw on low fire. The heater is 105% net efficient, with the modulation feature typically offering a saving of up to 30% on fuel costs compared to a non-modulating heater.

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.
