"Low-NOx atmospheric water heaters do comply with ErP" says Andrews

Manufacturer challenges view that future will be exclusively condensing technology

Andrews Water Heaters is challenging the view expressed last week that atmospheric water heaters will not be able to comply with current and forthcoming regulatory regime

Dan Martindale, sales director contends that despite some manufacturers touting condensing boilers and water heaters as the only way to comply, this is simply not true.

He said: “Although condensing water heaters can achieve maximise efficiency levels, for properties with an existing stock of atmospheric water heaters, a like-for-like replacement is the quickest and easiest way of meeting the forthcoming round of Ecodesign requirements.”

Mr Martindale noted that new models of atmospheric water heaters, such as the company’s latest range, incorporate an ultra-low-NOx burner that plays the same role in reducing emissions as the premixed burners  in condensing water heaters.

This means building managers wouldn’t have to switch their existing water heaters to a condensing system in order to comply, the company contentds.

Mr Martindale said: “Moving to a condensing system involves the replacement of flue systems; removal of condensate discharge longer change over times (resulting in longer down time for business); and, in most cases, will require considerable pipework alternations. Therefore, by upgrading to an ErP compliant atmospheric water heater, existing users can save time, money and hassle.”

He added that building managers should not panic: “With just over four months to go until the low-NOx levels become mandatory, specifiers and building managers should review their current systems but need not panic that they’ll have to carry out a massive upgrade before September. The prospect of complying with another round of ErP changes may seem daunting but the requirements are easily achievable with today’s high efficiency, low NOx water heaters. What’s more it will result in a cleaner environment, bigger energy savings and reduced emissions for all.”

Andrews Water Heaters said it offers both condensing and non-condensing water heaters for commercial use that comply with the Ecodesign requirements that come into force on 26 September 2018.
