It's there, inside the cabinet. Retrofit kit available for older ones when there is a need to change it out.

laars endurance EBP 110

Three fam we have had a boiler section crack on the sole boiler running an indirect. Decided to go with 3 laars endurance EBP 110. Installed first one a couple of weeks ago and it went in fine.

Got second and third one to cellar floor today and noticed a difference between them. All three are model EBP 0110 NAiF2AX. Reading the side plate the 2 delivered today were manufactured a couple of months ago. And the one we installed a couple of weeks ago was made around 2 years ago.

The visual difference is a switch on the domestic cold water which is in schematics with the newer ones. The older one is currently running all 3 apts (they are small one bed units) and we have had no complaints. The question is - on the older made one with no switch sensing hot water being drawn - should that switch be added if its possible? Does the electronics support adding that switch to the older one?

so

when hot water is drawn from the unit does the internal circ pump come on to pull water through heat exchanger? If so does the display show the pump on (would be top left led)?

1. Yes

2. No, but BFT will show, which indicates flow, etc.

BFT = Boiler Flow Temp.

Endurance domestic flow switch

Hi Allen,

All of the Endurance models have a flow switch that allows the boiler to fire when domestic hot water is drawn.

The location of the flow switch has changed recently, from inside the jacket cabinet, to a location just outside the jacket.

City water pressure provides the flow through one side of the flat plate heat exchanger, and the boiler pump provides the flow through the other side. The flow switch enables the boiler pump, and provides for domestic priority over the space heating demand.

If you have any additional questions about the models you have please contact me directly at the factory at 603-335-6300 x 562. I'm in from 8:00 to 5:00 Eastern time.

Sincerely,

Paul Bock
