convert gravity system to pump

TK500

Hello All
I'm needing some advice on the best options for converting a gravity hot water system into a pump style system. The house was built in 1892 and is on the historical register and the owner needs to maintain the existing radiators. Any help would be great!!

A mod/con(s) work great if you do it right. Flushing out sediment and protecting the new boiler(s) from debris is very important.

You need to start with an accurate heat loss calculation and radiation survey of the house.

Here's a thread with pics on one we did a couple of weeks ago:
