History

Angelo Pistoftzian, Owner and President, established ThermOil in 1983 to meet a rapidly growing need for a reliable provider of heating oil and boiler services in Watertown and the surrounding area.

With Bachelors and Masters degrees in Chemical Engineering from Northeastern University, and years of practical experience, Angelo combines an in–depth understanding of fundamental principles with a hands-on approach to daily operations. Angelo oversees every project from start to finish, and makes personal visits to work sites a priority.

Over the last 25 years, ThermOil has expanded from a local heating oil business into a regional incorporation offering Heating, Cooling, and Plumbing services to clients throughout Eastern Massachusetts.

Our motto is also our business model, and underscores our promise to provide
Total Customer Satisfaction.
