1:01DIY Greenhouse Heating: Reservoir and Pressure Release — Part 6 of 8
In Part 6, I explain the multiple purposes of the open water reservoir. It keeps the system filled when water evaporates and provides a place for air bubbles and excess pressure to escape at the system’s highest point. #HydronicHeating #GreenhouseSetup #DIYEngineering

1:01DIY Greenhouse Heating: Complete System Overview — Part 7 of 8
In Part 7, I explain why this is an open system and show the pump, reservoir, pressure-release setup and radiator lines working together. This system keeps my greenhouse plants warm throughout the Connecticut winter. #ConnecticutGardening #GreenhouseHeating #RadiantHeat

1:01DIY Greenhouse Heating: Calculating the BTUs — Part 3 of 8
In Part 3, I use the system’s 7.66-gallon-per-minute flow rate and a 10-degree temperature difference to calculate approximately 38,300 BTUs per hour. I also begin explaining the purpose of the water reservoir. #BTUCalculation #GreenhouseHeating #DIYHeating

0:58DIY Greenhouse Heating: Full Explanation — Part 1 of 8
In Part 1, I introduce my custom greenhouse heating system and explain how I modified a 30,000-BTU natural-gas furnace. Stainless-steel tubing circulates heated water to the radiant floor while the furnace also warms the greenhouse air. #GreenhouseHeating #DIYGreenhouse #RadiantFloorHeating

0:34DIY Greenhouse Heating: The Final Results — Part 8 of 8
In the final part, I show the tropical and citrus plants this system helps me grow in Connecticut, including citrus planted directly in the ground. Maintaining a stable temperature allows these sensitive plants to remain healthy through the winter. #GrowingCitrus #TropicalPlants #WinterGardening

1:01DIY Greenhouse Heating: Radiator Fins Explained — Part 5 of 8
In Part 5, I show the radiator fins positioned around the greenhouse and explain how they release additional heat into the space. The water circulates through each section and then returns to repeat the cycle. #RadiatorHeating #WinterGreenhouse #DIYSystem

1:01DIY Greenhouse Heating: How the Water Circulates — Part 4 of 8
In Part 4, I show how the reservoir keeps water in the line and how the circulation pump moves it through the entire system. The heated water travels through the radiant floor and radiator lines before returning to the furnace. #HydronicSystem #RadiantFloor #GreenhouseProject

0:57DIY Greenhouse Heating: Measuring the Heat — Part 2 of 8
In Part 2, I explain how I measure the temperature difference between the hot water leaving the furnace and the cooler water returning. I also introduce the formula used to estimate how many BTUs the system transfers each hour. #HydronicHeating #GreenhouseDIY #RadiantHeat
