HYDRA. FOR THE ULTIMATE HYBRID HEATING SYSTEM WITH SEAMLESS HEAT OUTPUT IN ANY WEATHER.

Combine renewable energy with an existing combi boiler to create the ultimate hybrid energy-efficient heating system that works seamlessly and effectively all year round.

WHEN TEMPERATURES FALL, HYDRA STEPS UP

Inta Hydra is a new hybrid solution for homes which currently have a working combi boiler installed. You can install an energy-efficient heat pump without removing the existing boiler, and there’s not need to add a hot water storage tank. Other existing hybrid systems can prove to be very expensive, and often require a large amount of space.

When an Air Source Heat Pump cannot provide heat, the Inta Hydra allows the original combi boiler to operate, providing constant heating, even during the coolest temperatures.

When the heating demand becomes greater than the heat pump can meet, the Hydra’s programmable control monitor will, after a series of timed-out delays, revert to using the combi boiler for heating the home.

HYDRA FEATURES SMART CONTROLS FOR AN UNINTERUPTED HEAT SUPPLY

Inta Hydra is a new hybrid solution for homes which currently have a working combi boiler installed. You can install an energy-efficient heat pump without removing your existing combi boiler and without adding a hot water storage tank. Current hybrid system methods can prove to be too expensive and require too much space.

When an Air Source Heat Pump cannot provide enough heat, the Inta Hydra automatically instructs the original combi boiler to operate, providing constant heating, even during periods of extreme cold temperatures.

When the heating demand becomes greater than the heat pump can meet, the Hydra’s programmable control monitor will, after a series of timed-out delays, revert to using the combi boiler for heating the home.

HERE'S HOW HYDRA WORKS

FREQUENTLY ASKED QUESTIONS

How does Inta Hydra work?

Hydra calls upon the gas boiler when the heat pump cannot meet the heat load demand, or is not functioning / out of service. Timed out delays stop unnecessary switching of the heat source.

A Hybrid heating system can be an electric heat pump combined with another technology, which could for instance be solar, but is most often a combi gas boiler. Two different energy sources are combined to provide heating and/or domestic hot water to a building. The operation of both heating sources is managed by one control unit; Inta Hydra.

The hybrid heat pump can de defined as a ‘package solution’, where two energy sources can complement each other and work as a single unit. Hydra is an installation where a heat pump is installed alongside a secondary, existing heat source, or is specified later as an additional heat source.

There are several ways to optimise the efficiency of an air source heat pump system for UK conditions.

By creating a hybrid heating system which features a new heat pump working in conjunction with an existing combi boiler installation you can benefit from the ecological and cost benefits of an air source heat pump, whilst knowing that should the heat pump fail or the temperature levels inside drop, the backup combi boiler system will serve as a stopgap and kick in.

Consider a high temperature heat pump so existing heat emitters and pipework don’t need replacing.

Making sure the property is as well insulated as possible will also increase the effectiveness of an air source heat pump.

Heat pumps run at lower temperatures. New advances in refrigerant technology are creating heat pumps that can run at higher temperatures, but still limitations apply when demand outpaces supply. A hybrid system can bridge the gap and provide seamless and consistent heat that is both cheaper and more environmentally-friendly than a gas boiler alone, and more consistent than an air source heat pump by itself.

If the heat pump has weather compensation technology then in very cold weather it will be working to it’s maximum output.

That’s down to the system design and the sizing of the heat pump. With good design the heat pump output will cope with the heat loss and comfort levels required. Where a backup is required, or in instances where the heat pump is unable to cope with the heat requirements, Inta Hydra can fill the gap and provide an uninterrupted heat supply.

Heat pumps are the best eco-friendly alternative to fossil fuel based heat production.

This will differ for each application, but a Hydra system could reduce costs significantly. Get in touch to find out more about Inta Hydra – contact us.

Affordability. Lower installation cost, up to 50% off a full conversion installation.

A hybrid heat pump system such as Hydra ensures uninterrupted comfort, reliability as well as the environmental benefits that come from the main heat source being the air source heat pump, with a gas boiler backup options option for extreme weather events or in the event of a heat pump malfunction.

There is also minimal disruption to the home, Hydra doesn’t need much in the way of new pipework, and a new hot water cylinder is not required.

Transition to a low carbon energy, and move up to COPs of 2.5 and more whilst enjoying the benefits of having two sources of heating, the main heat pump provider and a backup combi boiler for emergencies.

Hydra can be used alongside an existing combination boiler to continue hot water provision, utilising the existing control system.

Yes, installing a hybrid system such as Inta Hydra allows you to add a new air source heat pump to an existing gas combi boiler installation.

Consider a high temperature heat pump so existing heat emitters and pipework don’t need replacing. Make sure the home is well insulated and upgrade insulation where possible.

Design the system for the heat pump to deliver 100% of the calculated heat load. The combi boiler will deliver hot water, reducing the output required of the heat pump.

Hydra uses a smart electronic control strategy. A single master controller should manage heating operations so that the primary heat source (the heat pump) provides heating to the designed heat loss 100% of the time under normal operation conditions.

The secondary heat source is only called upon when the primary heat source is unable to meet the heating demand, or is out of service. The two heat sources should never run together at the same time.

For a UK new build, heat pumps are the best solution. For older properties, hybrid systems are the ideal way to reap the environmental and cost-saving benefits of a heat pump system, whilst maintaining the reliability and peace-of-mind that the gas combi boiler system is there as a reserve should the heat pump be unable to meet the heating demands.

By using a hybrid system such as Inta Hydra, 80% of the space heating demand is delivered by a greener technology that is around 3 times more efficient than a highly-efficient gas boiler that would gave energy efficiency of less than 1. On a hybrid system, where the heat pump meets 80% of space heating demand, and a gas boiler covers the remainder, you can increase energy efficiency to a COP of around 2.6.

Inta Hydra Hybrid Heating System

An overview for Heating Installers / Engineers

The Inta Hydra is a single master controller designed to integrate a heat pump into an existing boiler system, creating a hybrid domestic heating system. ​ It prioritizes the heat pump (primary heat source) for energy efficiency, only activating the boiler (secondary heat source) when the heat pump cannot meet the heating demand or is out of service. ​ The system ensures only one heat source operates at a time, with timed delays to prevent unnecessary switching. ​

This system is ideal for creating an efficient hybrid heating setup, leveraging the heat pump as the primary source while ensuring seamless boiler backup when needed. ​ All settings are adjustable via a locked installer menu. ​

Key Features

  • Energy Efficiency: The heat pump should be designed to meet 100% of the calculated heat load. ​ A high-temperature heat pump is recommended to avoid replacing existing emitters and pipework. ​
  • Flow Requirements: For an 11kW ASHP, a flow rate of 31 l/min (1.86 m³/hour) is required. ​ The 1” actuated ball valve ensures minimal pressure drop. ​
  • Pre-Wired Assembly: Includes Grundfos UPM3 Auto 25/60 pump, AQD actuator, and PT1000 temperature sensor (T1). ​ Optional sensors (T2, T3, T4) are available for defrost detection, high return temperature protection, and weather compensation.

Controller Features

  • Four preset operating profiles (adjustable). ​
  • Auto/Off/Manual operation modes. ​
  • Boost function for boiler intervention. ​
  • Boiler lockout during heat pump defrost cycles. ​
  • High return temperature protection for heat pumps. ​
  • Outside temperature monitoring for weather compensation. ​
  • Anti-legionella program for stored DHW. ​
  • Error messages for faulty/unconnected sensors. ​
  • Settings memory during power loss. ​
  • Factory reset and daylight saving auto-switching. ​

Operation Logic

  1. Normal Conditions
    • Stage 1 (Activation Delay): Heat pump starts after a delay (adjustable 1-30 minutes). Return temperature monitoring is inactive during this period. ​
    • Stage 2 (Deactivation Delay): Heat pump remains active while return temperature monitoring ensures the set point is met. If satisfied, the system switches off. ​
  2. Abnormal Conditions
    • If the return temperature is below the set point, the boiler is activated, isolating the heat pump. ​ Reactivation delay (adjustable 30-1440 minutes) prevents erratic switching, ensuring the heat pump resumes as the default heat source after the delay. ​

Installation Notes

  1. Connections: Includes isolation valves for heat pump and boiler flow/return lines. ​ Two versions are available:
    • HCU0100-A: Heating connections flow/return upwards. ​
    • HCU0100-U: Heating connections flow/return downwards. ​
  2. Optional Accessories: PT1000 sensors for advanced monitoring and a white gloss cover (HY-AC2WH) for concealment.

Dimensions

  • The Inta Hydra unit measures approximately 500mm x 160mm.
