5800056

The Grundfos 5800056 Boiler Circulator Pump is a reliable and efficient solution for circulating water in central heating systems, specifically designed for use with wood-burning boilers. This pump is part of Grundfos' Woodmaster series, which is engineered to meet the unique demands of wood-fired heating applications.

The pump features a robust, cast-iron housing that provides excellent protection against the thermal shock and mechanical stress commonly encountered in such systems. The pump's impeller is designed with a special profile that ensures efficient circulation of water, even when the system is starting up or when the water temperature is low.

The Grundfos 5800056 Boiler Circulator Pump is equipped with a thermostat-controlled start-stop function, which automatically starts the pump when the water temperature drops below a certain level and stops it when the temperature rises above a pre-set limit. This feature helps to ensure optimal heating performance and energy efficiency.

The pump also includes a built-in pressure relief valve, which protects the system against excess pressure and prevents damage to the pump or other components. The valve is adjustable, allowing users to set the desired pressure level to suit their specific heating system.

The Grundfos 5800056 Boiler Circulator Pump has a flow rate of 20 to 78 liters per minute (L/min) and a maximum head pressure of 10 meters. It is suitable for use with water temperatures up to 95 C (203 F) and can handle solids up to 3 mm in size. The pump is also easy to install, with a simple plug-and-play connection that requires no additional wiring or external control unit.

Overall, the Grundfos 5800056 Boiler Circulator Pump is a high-quality, durable, and efficient solution for circulating water in central heating systems powered by wood-burning boilers. Its thermostat-controlled start-stop function, adjustable pressure relief valve, and robust design make it an ideal choice for homeowners and heating professionals seeking reliable and energy-efficient heating solutions.

The Grundfos 5800056 boiler circulator pump, also known as the Central Woodmaster model, is a commonly used circulator pump for heating systems. Here are some pros and cons of buying this particular model:

1. Energy Efficient: This pump is known for its energy efficiency, as it is designed to operate at low power consumption while still maintaining effective circulation.

2. Quiet Operation: The pump operates quietly, making it a good choice for installations where noise levels need to be kept low.

3. Robust Design: The pump is built to withstand the rigors of continuous use in heating systems, with a durable housing and corrosion-resistant impeller.

4. Easy Installation: The pump is relatively easy to install, with a standard thread connection and a simple wiring setup.

5. Reliable Performance: The pump is known for its reliable performance, with a long lifespan and minimal maintenance requirements.

1. Price: The pump is more expensive than some other circulator pumps on the market, which may be a deterrent for some buyers.

2. Size: The pump is larger than some other circulator pumps, which may require additional clearance for installation.

3. Limited Capacity: The pump is not suitable for large heating systems or high-flow applications.

The Grundfos 5800056 boiler circulator pump is a reliable and energy-efficient choice for heating systems, with a quiet operation, robust design, and easy installation. However, it may be more expensive than some other options and may not be suitable for large heating systems or high-flow applications. Ultimately, the decision to purchase this pump depends on the specific requirements of your heating system and your budget.

If you have a mid-sized heating system and are looking for a reliable, energy-efficient, and quiet circulator pump, the Grundfos 5800056 boiler circulator pump is a good choice. However, if budget is a concern or you have a larger heating system, you may want to consider other options that offer similar performance but at a lower cost.

Ecm motor technology dramatically reduces power consumption versus traditional PCs pumps. Grundfos umps 20-78 f ecm circulator p/n 5800056: drop-in alternative to a taco 011 same footprint, similar performance, far lower power draw. For systems that run day and night all winter, difference matters. Long underground supply and return runs.

It is the same physical size class as a taco 011 and delivers near-identical performance, allowing it to fit in location handle work while using significantly less electricity. Soft-start, self-venting, and dry-run protection for reliable operation fewer callbacks. Portage main. Plate heat exchanges and large duct coils.

In a typical outdoor boiler installation, this pump is well suited for systems with up to approximately 500 feet of equivalent length , once underground piping, plate heat exchanges, elbows, valves, and other fittings are factored in. Typical applications: outdoor wood boiler main circulation loops. The Grundfos umps 20-78 f is a high-efficiency ecm variable-speed circulator built for demanding hydroponic and outdoor wood boiler systems. But it also burns a lot of electricity doing.

Central boiler. Compatible / commonly used with outdoor boiler brands: crown royal stoves. Three constant-curve settings for system tuning and efficiency.
