Customer Brief:

In May 2023 Warmco were asked to install three Winterwarm, natural gas fired, suspended, space heaters, into this 20,000 square foot, manufacturing facility in Stanley, County Durham.

Features of the Heating System:

The 20,000 square feet  area within these manufacturing premises was not being adequately heated by three Combat CUHA gas unit heaters, which had faulty heat exchangers.  Our customer therefore invited us to heat the space with modern, efficient heating equipment, which could get the space up to the target temperature quickly.  To this end, we installed three Winterwarm, XR50, gas fired, suspended unit heaters, which each have a maximum heat output of 50.7kw, and can be used to get the space quickly to a high temperature.  However, once the control panels detect that this has been achieved, the heater has the capacity to modulate its heat output down to 31.5 kw, to ‘top up’ the heat as required.  This 95.6% nett efficient product, can typically offer a fuel cost saving of up to 30% against standard non-modulating models. (These heaters comply with ErP as determined by EU 2015 / 1188, they have a ten-year warranty on their heat exchangers, and they carry a 2-year parts and one year labour warranty). This heating was installed over a three-day period, and by working closely with the site supervisors, and employing the services of the approved roofing contractor to seal the flues, our engineers were able to minimise any potential disruption to the customer’s all-important manufacturing activities.

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.
