Purchased a tubular heater for my garage a needed a plumber to install. He had to increase the pipe size off of the meter due to the amount of load on the system. The heater is about 10 feet in the air. He had all the supplies he needed and a helper. It was a cold day and he worked with no stoppages or complaints. As the home owner I assisted where I could. The install might have taken 4 hours max. For a very small job I thought it might be difficult to find someone but he was great.
