After the furnace is stopped, the boiler water is discharged, cleaned and filled with clean water, the power is cut off, and the valve is closed. Dry maintenance means that after the furnace is shut down, the boiler water is released, the dirt in the furnace is washed out, the boiler ...
Eilian Siar was also found to have the highest water costs, with its average cost of £154.72 per year (over £19 more than Castle Point—the next costliest place). A string of low-efficiency scores were found in the East Midlands, with two places each from the counties of Leicesters...
Try turning the boiler off and on again Check yourcondensate pipes aren’t frozen If your boiler has a cold water tank in the loft, check the float ball valve hasn’t got stuck; if it has, the water level will be low or zero, in which case gently try to free its arm without using...
Most of these units were originally designed for base loaded operation and not designed to accommodate frequent on/off cycles. The stresses placed on the weld joints, headers, drums and attachments between expanding and contracting parts, can cause failures after a finite number of cycles. ...
2. When the gas connections are completed, it is necessary to perform a gas leak test either by applying soapy water to all gas fittings and observing for bubbles or by using a gas leak detection device. • The micro-boiler and its individual shutoff valve must be disconnected from the ...
