With my conversion from oil to gas (burnham pvg-5 bolier )went well yesterday (in 9 degree weather). Thanks for your help. I am concerned about the indirect water heater installed. We agreed on a crown mega-stor 50 and wound up with a Lochvinar sit 50. In installers told we that the supplier was out of the crown. Any opinion on the quality/price/performance? Did I wind up with a lesser indirect water heater than the Crown ? thanks, jp
