Page 2: Technical Specification
INTRODUCTION The HSR Series units are designed to supply hot water for handwashing, dishwashing and general purposes to cloakrooms, canteens and kitchen areas. Containing an integral cold water cistern, they are ideal for installations where the cold feed is from the mains supply but an unvented situation is impractical. -
Page 3: Important Installation Points
1.0 IMPORTANT INSTALLATION POINTS 1.1 Ensure that the wall or supporting structure is of adequate strength to support the heater. (Refer to table 1.) 1.2 The Water Regulations require a minimum of 350 mm unobstructed space above the heater lid to allow the float valve to be replaced. However, a space of 200 mm is sufficient to replace the HSR Series float valve. - Page 4 2.1 Decide on the best position for the heater taking account of paragraphs 1.2 and 1.3 and inlet and outlet connections. The float valve and overflow assembly can be fitted on either side of the heater. 2.2 Using the template provided mark the position of the top two fixing holes. Before drilling the wall ensure there are no hidden services such as water, gas or electrical cables embedded in the area of the wall to be drilled.

Questions and answers
Hi we have been out to a heater that has water going into but none coming out. What could be the issue please ?
Possible issues if a Heatstore HSR25 heater has water going in but none coming out:
1. Thermal Cut-Out Tripped – Check if the thermal cut-out has been activated. If so, reset it and inspect the thermostat for failure in the closed position or an excessively high setting. Replace if necessary.
2. Element Failure – A faulty heating element may prevent proper operation. Replace the element if needed.
3. Thermostat Faulty – If the thermostat has failed in an open circuit, it may prevent heating. Check and replace if required.
4. Blocked Outlet or Pipes – Ensure that outlet pipes are not clogged or obstructed, preventing water flow.
Check these components systematically to identify and resolve the issue.
