Wilo assistant โ The entire world of pumps The pump specialist WILO SE has made the entire world of highly efficient pump technology accessible on the smartphones and tablet PCs. As an easy-to-use and mobile application, the app offers support in the areas of planning, customer consultation and installation. In addition, the user is presented with a plethora of valid selling points for energy efficient, economical and environmentally friendly pump technology for heating, air-conditioning and secondary hot water circulation. A large proportion of the data content and functions are installed directly onto the smartphone or tablet and are therefore available to the user even in the absence of a mobile internet connection or WLAN. This way, the user can avoid overloading his/her data volumes and is not limited in anyway by the reception conditions prevalent at the site of use. Functions: > Smart Connect: With the help of the Wilo-Smart Connect function, you can easily access the smart and smart-enabled pumps and pump systems from Wilo and make the desired settings and controls. > Interactive replacement guide: simply enter the name of the pump to be replaced and you will be provided with a recommendation of the suitable, high-efficiency Wilo replacement pump. This service can be used in conjunction with thousands of commercially-available, old pumps that were manufactured in 1975 or later. > Energy savings calculator: calculates the potential savings in terms of energy costs and CO2 emissions by comparing implementation of an energy-saving Wilo high-efficiency pump with that of an uncontrolled heating pump. > Catalogue: displays the catalogue description for Wilo pumps. > Pump dimensioning: according to the specifications of the desired pump duty points, the Wilo server adopts the pump dimensioning and recommends the suitable Wilo pump in a matter of seconds. > Fault signal assistant: the "Fault signal assistant" tool contains fundamental information on possible fault signals that may be shown on the display of certain Wilo pumps. With some fault signals, the tool specifies the cause of the fault, describes the error and specifies possible remedies, in addition to basic information about hazards. > Unit converter: conversion of the fundamental physical units > News: up-to-date information > QR Scanner: Scan any QR code > AR Scanner: Scan product images of Wilo products in brochures or at trade shows for additional information such as videos, animations or direct links to the series description The Wilo Group is one of the world's leading premium providers of pumps and pump systems for building services, water management, and the industrial sector. Over the past decade, we have transformed from a hidden to a visible and connected champion. Today, over 9,000 employees work for Wilo worldwide. We place great emphasis on transparency for all employees, partners, and customers.

Quickly calculate a radiator's heat output at different water and air temperatures. Select the radiator that fits, based on heat losses and water temperature. Don't undersize or oversize and ensure the best energy efficiency possible.ย Low water temperature (e.g. with heat pump as heat generator) can greatly increase energy efficiency and keep the cost down, but it still needs to provide enough heat to keep the room or the building warm. That's why larger radiators are needed in such cases. Find out exactly how large quickly using this app. Anywhere, anytime, fast and simple. ** Note: metric units only. *** This app is totally free - no ads, no in-app purchases. No account needed, no log-ins, no user data needed nor collected. *** A radiator's heat output is highly dependent on temperature of water entering and leaving the radiator. Nominal heat output of a radiator can be found in a catalogue or a technical brochure. The nominal heat output is valid only at the conditions specified in the catalogue. This application will calculate the heat output of the selected radiator at conditions specified by the user. This is useful for the selection of the right size of a radiator when designing a new heating system, as modern heating systems tend to use lower water temperatures than those specified in catalogues. The reason is simple: lower temperatures mean higher energy efficiency and lower cost. The application can also be used for calculating the cooling output of convectors and fan-coils at various conditions. The application is available in English, French, German and Italian languages. The application does not contain ads.

Verdict
The clearest difference is review sentiment: RadiatorOutput at 100% against Wilo's 66%. RadiatorOutput also leads on device support (4 vs 2) and iOS requirement (15.0 vs 18.6). Wilo's advantage is update cadence (every 3 weeks vs every 8 months). On price, ads, in-app purchases and monetization model there is nothing between them.
