Elco offers smaller wall-hung boilers
Elco UK’s Thision S range of light-commercial gas-fired wall-hung condensing boilers are available with outputs of 25, 35 and 50 kW and offer net efficiencies up to 111%. Standard features include built-in pump and stainless-steel heat exchanger. These boilers come with a 2-year warranty for parts and labour. There is a free service after the first year of operation.
The turndown ratio is 10:1, making these boilers well suited to well insulated buildings with a low heating demand throughout the year.
The built-in pump has an Energy Efficiency Index (EEI) of less than 0.23, which already meets the 2015 ErP requirements. The new pump and motor considerably reduce flow noise in the heating system.
Thision S boilers have control options for one or two heating circuits (with or without variable-temperature mixing valves) to be connected, plus a domestic-hot-water cylinder. Each heating circuit can have separate time schedules. These boilers have full weather compensation based on outdoor temperature.
