I have a Peerless Purefire boiler (80,000 BTU). The hoses (#1 in picture) that connect from the "combustion chamber" and "vent system", to the tank, leak. I have tried tightening the plastic clamps that come with the boiler, and even used metal hoes clamps, but nothing has worked. Is there a better way to make sure that this does not leak?

The one we had in for testing purposes worked fine in the clamp (s) departments but I recommend you contact them. Please contact Peerless Boiler Company so they can answer your questions and concerns. This is a new style boiler and it is possible they are having a problem with the connection. I am sure you are aware that this unit is to be installed by a authorised HVAC company to maintain the warranty. This unit is NOT setup to operate properly as shipped by the factory and will need technical adjustments as well as special tools to perform same. Just a heads up.

I will definatley contact Peerless. Actually, it's usually the same gentleman who answers the phone. This boiler is not mine; it is one that I installed for a customer of mine. I usually stay with Weil-McClain or Knight, when installing a mod-con boiler. I went with a suggestion, of one of my suppliers (sure wish your review was out back then), and it seems like it has been a lemon. Do not get me wrong, I have had success with Peerless products, but not, this Purefire.

Today, I noticed that the leak had gone away (I adjusted the clamp), but there is still water between the two canisters, and the metal base of the boiler. Seems like there might be some condesation occurring, since the water in the canisters is hot, and the metal is cold. I was thinking of putting some sort of thermal break. Do you have any suggestions?

The condensate system was designed to solve one problem and prevent another but in this case it seems to be causing a small problem itself.

Check the connections at the U shaped hose at the bottom ends of both containers where they innerconnect to make sure it is leak proof. Call Peerless for further advise.

There are so many mod-cons out there it is hard to keep up with all of them.

I called Peerless and they told me to put a piece of cardboard underneath the containers. Personally, I think some rigid foam insulation would work best.

But cardboard is absorbent. LOL Other than that how is it running for you.

It actually runs pretty good. This was the first Purefire that I installed. Normally when installing a high-efficient boiler, I go with Weil McLain and Viking. I did have some other problems with this boiler... the relief valve and pressure gauge both went, and there was a minor crack, on both couplings, that comes on the supply and return.
