Looking for contractor

I'm thinking of converting my home's hydronic system to a different control setup and am interested in finding a hydronic pro in the Vancouver BC Canada region who really knows his system engineering. This conversion will be a major change so I need someone who knows his theory. Does anyone have any recommendations of who to call?

Ever tried

the site from CIPH? There my be a contractor on there too. I`m a member, but in Ontario.

Also try the TECA site (thermal environmental comfort ****'n. of B.C.)

what do you have in mind?

Specifically - changing to what type of system? EG, if changing to Viessmann - phone their Langley office. Other suppliers & manufacturers will have similar representatives able to help and/or recommend a contractor. Most suppliers have in house hydronic or warm air heating specialists as well.

Well, i don't want to bill myself more highly than I should, but you could call me at 604-823-6819. I am very expensive, but you don't have to retqin me after our first visit if you do not feel you are getting value for your money.

I currently have a radiant in-floor system with a very simple control setup. When a zone calls for heat the boilers are enabled and the circulators run. The boilers regulate their own temperature with local aquastats and drive a local loop. Distribution water taps this loop using a temperature modulated bypass valve. The zone relays are driven by basic wall thermostats. Its a fairly large system with too many zones (16 in all).

Now, the problem with this system, which is now about 5 years old, is that it suffers from "ticking" noise from the PEX tubing in the walls when a cold zone calls for heat. When a cold zone calls for heat, hot water is routed to the zone and the cold PEX is quickly heated and expands rapidly, and where it rubs against wood framing, I get ticking noises as the tubing expands. You would think the ticking would be faily quiet, but in fact it is surprisingly loud in several places and marginally annoying in many spots. Most of the problem areas are in the walls near manifolds, or where tubing is routed between floors, not in the floors themselves.

I have the option of opening up walls and putting sleeves on tubing where needed, but this would require a lot of holes in the drywall, and working around substantial millwork finishing, and an expensive paint job following. So I looked for other solutions.

I posted for advice about a year ago here in this forum and at that time received some very good and interesting suggestions on how to deal with this. In addition, I consulted with the plumber who installed the original system. Out of all that I have the impression that I could remove all of the problem ticking by changing over to a constant flow system, where the water temperature is slowly modulated using a reset controller based on outside air temperature. A year ago, some posters suggested that I could modify my system relatively economically to a "virtual constant flow" system using an intermediate heat exchanger tank whose loop-side water was modulated. The slow change of temperature of the circulation water, as slow as the outside temperature changes, would insure that expansion tick noises in the tubing were very widely spaced in time and hence not obvious.

My favorite heating contractor didn't seem interested in looking at this idea so I want to hook up with someone that can do the detailed engineering of this kind of conversion.

Sorry for the long explanation, but I hope that answers your question.
