We live in PML and had an old water heater that kept running out of hot water, so we wanted to update to a tankless water heater. Optimized Plumbing advised us on choosing an appropriate a tankless water heater size for our 2 bathroom cabin and also installed in only a few hours. We’ve had the system for about a 1 year, now, and we have had no issues or even a single leak and we love having plenty of hot water on-demand. The only draw-back to having a tank-less system is that it takes a bit longer (especially in the colder months) for hot water to get hot, but we can live with that. Bottom line is that Optimized Plumbing are responsive, on-time, clean and professional.
